CVE: CVE-2023-30960
Affected Products / Versions: job-tracker, versions less than 4.645.0
Publication Date: June 29, 2023
Summary
A security defect was discovered in Foundry job-tracker that enabled users to query metadata related to builds on resources they did not have access to.
Background
Foundry job-tracker is a service that provides a fast, permissioned cache of foundry builds and a build state UI.
Details
Foundry job-tracker provides several API endpoints to query metadata related to builds, and provides filters for those results such as underlying resource RIDs, time of creation and build status.
It was discovered that by replacing a RID in the filter with one the user did not have access to, they could still query build metadata for that resource if it existed. Furthermore, by removing all entries for the filter the service would return metadata for all build objects in its cache, including those that related to resources the user did not have access to.
Build metadata that was impacted includes: The RID of the build, the username and UUID of the build’s author, start and finish time of the build, the RIDs of the input and output datasets, Job metadata related to the build and Build Status.
Remediation
This defect was resolved with the release of job-tracker 4.645.0. The service was rolled out to all affected Foundry instances. No further intervention is required.

CVE: CVE-2023-30963
Affected Products / Versions: foundry-frontend, versions less than 6.229.0
Publication Date: June 29, 2023
Summary
A security defect was discovered in Foundry Frontend which enabled users to perform Stored XSS attacks in Slate if Foundry’s CSP were to be bypassed.
Background
Foundry Slate is an extensible WYSIWYG (“what you see is what you get”) web-based application used to quickly create interactive visualizations of aggregate enterprise data.
Details
When creating Queries in Slate, users have the ability to create folders to assist with organization. If a folder was created with an XSS payload as the name, it was discovered that when attempting to move a query into any folder using the dropdown menu, the XSS would be triggered. This XSS was blocked by Foundry’s CSP and would therefore require a CSP bypass to become effective.
Remediation
This defect was resolved with the release of Foundry Frontend 6.229.0. The service was rolled out to all affected Foundry instances. No further intervention is required.

CVE: CVE-2023-30958
Affected Products / Versions: foundry-frontend, versions less than 6.225.0
Publication Date: June 29, 2023
Summary
A security defect was identified in Foundry Frontend that enabled users to potentially conduct DOM XSS attacks if Foundry’s CSP were to be bypassed.
Background
Foundry Frontend’s Developer Mode allows users to interact with Foundry in a manner intended for technical users and developers on Foundry. A defect was identified in how the Frontend handles redirects from the Developer Mode page that enabled DOM XSS.
Details
The developer mode service implements a GET parameter ‘redirectTo’ that is used to determine what page should be navigated to when a user clicks the appropriate button in the UI.
It was found that Foundry Frontend used this parameter in conjunction with a sink without sanitization which could lead to DOM XSS attacks. The attack proof-of-concept was blocked by Foundry’s strict CSP which means that the vulnerability could not be utilized to effect without also finding a CSP bypass.
Remediation
This defect was resolved with the release of Foundry Frontend 6.225.0. The service was rolled out to all affected Foundry instances. No further intervention is required.

Affected Products / Versions: workspace, versions less than 7.7.0
Publication Date: June 26, 2023
Summary
A security defect was identified in Foundry workspace-server that enabled a user to bypass an authorization check and view settings related to 'Developer Mode’.
Background
Workspace ‘Developer Mode’ is a feature set in Foundry that affords privileged users the ability to interact with the Foundry Platform in a technical manner. Features include the ability to preview work-in-progress changes via a commit preview function and toggling in-development client-side features in the platform.
Details
An authorization check is made to discern whether or not a user should be entitled to view settings related to Developer Mode when requested. On a failure to authorize, the user would be presented with a UI prompt explaining they were not entitled to view the feature set. It was discovered that by using an intercepting proxy to edit inbound traffic related to the UI, a user could trick the frontend into rendering the prohibited features allowing them to browse and interact with Developer mode in a limited capacity.
Remediation
This defect was resolved with the release of workspace-server 7.7.0. The service was rolled out to all affected Foundry instances. No further intervention is required.

Affected Products / Versions: magritte-rest-source-bundle, versions less than 7.210.0
Publication Date: June 26, 2023
Summary
The magritte rest-source plugin prior to version 7.210.0 is vulnerable to an XML external Entity (XXE) attack.
Background
Foundry can integrate with external systems that expose a REST API. The REST API source may be used for workflows requiring interactive HTTP requests to external systems directly from Foundry applications via Actions. For example, you can create a Workshop application with a button that uses a webhook to calls a REST endpoint when clicked, connecting that application to existing workflows and source systems.
Details
Magritte rest-source plugin, specifically the XML extractor that performs XML response extraction from an HTTP endpoint response was found to be vulnerable to an XXE exploit which could have allowed a malicious user to exfiltrate sensitive files from inside the magritte agent.
Remediation
On Palantir-managed environments, the following services have been upgraded to patched versions which properly validate the XML document and safely parses it by disallowing external DTD. Customers which manage their own environments without Apollo should reach out to their forward deployed engineer or other Palantir POC.
Magritte-rest source if it is in use, to version >= 7.210.0 (Foundry only)

Affected Products / Versions: foundry-frontend, versions less than 6.228.0; issues, versions less than 2.510.0
Publication Date: June 26, 2023
Summary
A security defect was identified that enabled a user of Foundry Issues to perform a Denial of Service attack by submitting malformed data in an Issue that caused loss of frontend functionality to all issue participants.
Background
Foundry Issues enables users of Foundry to surface, find, and resolve problems that they encounter within Foundry by filing issues on certain types of resources. Issues have a state that shows at what stage in the management lifecycle they are currently in. Issues can be open or closed, but they also may be waiting for a response from the reporter for example.
Details
When an action is performed in an Issue such as making a comment or changing an Issue state, the record of the Issue is updated with the values that changed to keep a historical log of actions made. It was discovered that when making a request to change the state of any Issue a user could modify the state in an unexpected manner, and the malformed state would be persisted in the Issue record.
When Foundry Frontend attempted to render the Issue with the tainted Record, an exception would be thrown which resulted in a loss of functionality in Foundry Frontend when browsing the Issues app for all assignees of that Issue.
Remediation
This defect was resolved with the release of Foundry Issues 2.510.0 and Foundry Frontend 6.228.0. The services were rolled out to all affected Foundry instances. No further intervention is required.

Affected Products / Versions: campaigns, versions less than 0.623.0
Publication Date: June 26, 2023
Summary
Foundry Campaigns versions prior to 0.623.0 included an unauthenticated endpoint that would have allowed an attacker to disclose a private campaign without authentication.
Background
On June 8th, 2023 , it was discovered that an endpoint in foundry campaigns service could return details about a campaign without authentication/authorization. An attacker would need to know a target campaign ID and then query the vulnerable endpoint to return information about the campaign.
Details
The Campaigns app allows deployment teams to create (via an intuitive WYSIWYG interface) and schedule HTML email campaigns to dynamic end-user targets.
Remediation
The vulnerable endpoint was patched to require full authorization and authentication on the target resource. On Palantir-managed Foundry enrollments, the relevant services have been automatically upgraded to the fully-patched version.

Affected Products / Versions: comments, versions less than 2.267.0
Publication Date: June 26, 2023
Summary
A security defect was identified in Foundry Comments that enabled a user to discover the contents of an attachment submitted to another comment if they knew the internal UUID of the target attachment.
Background
Foundry Comments is a service that allows users to converse and collaborate within the context of a resource in the Foundry Platform.
Details
When uploading an attachment to a comment, the attachment is stored in Foundry’s primary datastore and a UUID representing it’s location is returned to the service.
When requesting to delete a comment with an attachment the UUID of the attachment is submitted as a part of the request to enable Foundry to display it as part of a confirmation prompt. It was discovered that a user could replace the UUID of the attachment they were attempting to delete in the original request with the UUID of an attachment they were targeting to discover it’s contents.
This would require the user to find the UUID of the targeted attachment, which is not trivial due to the nature of UUIDs.
Remediation
This defect was resolved with the release of Foundry Comments 2.267.0. The service was rolled out to all affected Foundry instances. No further intervention is required.

Summary
The Contour Service was not checking that users had permission to create an analysis for a given dataset. This could allow them to clutter up Compass folders with extraneous analyses they would otherwise not have permission to create.
Background
Contour is a point-and-click data exploration, analysis and transformation tool. Contour enables users to work with their data in a visual and iterative fashion making and tweaking decisions based on what they see.
Details
On Jan 5th 2023, a pull request was merged that removed an authorization check from contour. Following this, users would be able to create Contour analysis even if they wouldn’t otherwise have permission. Users would still need authorization to access the underlying datasets for any analysis they created. The only known security impact is that users may have been able to clutter up folders by creating contour analyses in places they wouldn’t have otherwise have permission to do so. This change was discovered and remediated on April 14th.
Remediation
Upgrade Contour to 9.642.0 or higher

Summary
A security defect was discovered in Foundry Issues that enabled users to create convincing phishing links by editing the request sent when creating an Issue. A fix was applied with Foundry Frontend 6.228.0 and rolled out to all affected Foundry instances.
Background
Foundry Issues enables users of Foundry to surface, find, and resolve problems that they encounter within Foundry by filing issues on certain types of resources. When creating an Issue in Foundry the request that is sent contains a ‘reporterPath’ parameter, the contents of which are used to create a URI that links to the location where the issue was raised. The contents of this are ultimately user controlled and can be changed to create realistic phishing links.
Details
No URI validation was performed on parameters submitted as part of the Issue creation request. Typically the submitted ‘reporterPath’ parameter is prefixed by the URI of the Foundry Deployment that the issue is raised on. By editing the ‘reporterPath’ parameter to include syntax related to HTTP basic auth, it was possible to generate a link that navigates to domains outside of Foundry that would still be prefixed by the Foundry Deployment URI, creating a phishing link that looks realistic.
Remediation
URIs are now checked on Issue submission to ensure they are correctly formatted, otherwise they are discarded. A fix has been applied to affected Foundry instances. No further intervention is required.

Summary
The Delegated-Media Service does not validate that users have permission to access a media resource. If an authenticated user guesses or is given an s3 URL which the delegated-media host has access to, they will be able to access it via delegated-media even if they otherwise would not have permission.
Background
Delegated Media is a service used as part of Palantir Gotham to access external media, such as media stored in s3 buckets.
Details
The Delegated-Media Service was initially intended to be deployed with an additional authentication layer which would perform authorization checks. As the service is currently deployed, it could be used to bypass authorization checks for media by passing it a URL for an external media object that the Delegated-Media Service has access to. Delegated-media 1.0.0 adds an authorization check, resolving the issue.

Publication Date: June 9, 2023
Summary
Multiple Services in video application server were vulnerable to an unauthenticated path traversal attack that resulted in an arbitrary file read/write/delete. The affected services have been patched and automatically deployed to all Apollo-managed Foundry instances.
Background
Video Application Server is a repository that hosts multiple services such as VHS (Video History Service), VCD(Video Clip Distributor) and DVD (Dummy video Distributor). …
video-application-server (VAS): Central video service that is responsible for surfacing available videos and integrating with the Gotham platform.
video-history-server (VHS): Service that is responsible for maintaining video archives and serving archived video.
dummy-video-distributor (DVD): Service that plays files on disk as live streams via ffmpeg or multicast.
Clips2 : Clips2 is built around a headless Chrome Browser and FFMPEG to support video clip exports
Details
On May 2nd, 2023 all of the services in VAS were found to be vulnerable to multiple unauthenticated path traversal issues due to missing validation on filenames which could have allowed a malicious user to read sensitive files on any of the impacted services filesystem or create/delete files as well.
Upon further investigation another service (clips2) was discovered to use a similar vulnerable pattern . Internal teams have audited the whole fleet and determined no true positive instances of the vulnerability being abused or exploited.
Remediation
VHS, VCD, DVD: All the vulnerable endpoint perform a correct validation on the filename parameters and also require authentication on all the resources. Clips2: The vulnerable endpoints were patched to perform correct validation on the filename parameters.
On Palantir-managed Gotham enrollments, the relevant services have been automatically upgraded to the fully-patched version.

Affected Products / Versions: comments, versions less than 2.249.0
Publication Date: June 06, 2023
Summary
A security defect was discovered in Foundry’s Comments functionality. A fix has been applied and rolled out to your Foundry environment. The vulnerability allowed an authenticated user to retrieve attachments tied to comments if the random UUID associated with that attachment was discovered.
Background
A security defect in Foundry’s Comments functionality resulted in the retrieval of attachments to comments not being gated by additional authorization checks. This could enable an authenticated user to inject a prior discovered attachment UUID into other arbitrary comments to discover it’s content.
An investigation revealed no known exploitation of this vulnerability.
Details
When adding an attachment to a comment, the Comments Service returns a UUID which is used as a locator for that attachment in our primary datastore Alta.
This UUID is appended to attachment insertions when creating new comments. It was found that no additional authorization checks were performed when negotiating retrieval of the attachment. This resulted in a situation where an authenticated party could inject a valid UUID, if it were discovered, to a comment creation request and leak the contents of the attachment associated with the injected UUID from an unrelated comment that they may otherwise be unable to see.
Due to the nature of UUIDs, successful exploitation of this vulnerability would require the user to discover a target UUID via other means, or otherwise invest considerable resources in attempting to brute force a valid UUID.
Remediation
This defect was fixed in Foundry Comments 2.249.0, and a patch was rolled out to affected Foundry environments. No further intervention is required at this time.

PLTRSEC-2023-17****Summary
Palantir discovered a software bug in a recently released version of Foundry’s Lime2 service, one of the services backing the Ontology. The software bug has been fixed and the fix has been deployed to your hosted Foundry environment. The vulnerability allowed authenticated users within a Foundry organization to potentially bypass discretionary or mandatory access controls under certain circumstances.
Background
A software bug in Foundry’s Lime2 service (versions 2.519.0 through 2.531.0) occurred, and resulted in the service not correctly verifying permissions when API queries were issued through Foundry’s Phonograph service under certain circumstances. The regression introduced by this software bug manifested in a way where authenticated users within a Foundry organization could potentially bypass discretionary or mandatory access controls applied to objects with discover permissions for their account.
A thorough investigation revealed no known exploitation of this bug on Palantir managed or on-premise environments.
Details
The vulnerability could potentially impact authenticated users’ front-end and back-end access. For front-end access, users with discovery (view) permissions on an object type may have been able to view the object type and observe aggregations related to the object type. For back-end access, the impacted phonograph search API endpoint may have returned a list of objects and associated properties that did not respect mandatory or discretionary controls. However, data returned via this API would respect GPS security constraints.
Successful exploitation of this bug via back-end access would require elevated permissions within Foundry, knowledge of the phonograph2 API endpoints, and specific resource identifiers, which are generally undiscoverable to non-privileged users.
For front-end access, users with discovery (view) permissions on an object type may have been able to:
- View the object type and observe aggregations related to the object type, such as the count of objects and properties.
- Access a small subset of Foundry user interface components, including Object Explorer, Workshop, and Search, possibly exposing some metadata to users.
- Direct loads or reads of object data (e.g., rows, columns) remained protected in all cases by role-based security controls and were not visible to unauthorized users. Despite these exposures, the risk of unauthorized front-end data access is considered low.
For back-end access, the impacted Phonograph2 API endpoints may have exhibited the following behaviors:
The API endpoints may have returned a list of objects and associated properties that did not respect mandatory or discretionary controls.
Data returned via impacted API endpoints would have continued to respect granular permission service (GPS) security constraints and only displayed data the requestor was authorized to view for the relevant policy. However, this could have inadvertently revealed object metadata to the requestor.
All other Phonograph2 API endpoints, such as the data load endpoints (e.g., getObject, getObjects, etc), continued to appropriately respect discretionary and mandatory access controls. Successful exploitation of this bug via back-end access would require:
Pre-existing elevated permissions within Foundry (e.g., ‘Ontology Administrator’).
Knowledge of the Phonograph2 API endpoints. Specific resource identifiers (e.g., GUIDs) which are generally undiscoverable to non-privileged users.
In certain cases, existing Slate dashboards may have relied on the discretionary permissions to limit the scope of the usage of the affected APIs for a subset of users of those dashboards. In such cases, users might have been inadvertently exposed to the list of objects and associated properties mentioned above. However, the likelihood of this occurring is believed to be low.
Remediation
The bug has been fixed as of Lime version 2.532.0, and the patch has been deployed to the affected Foundry environments. No ongoing risk of unintended data visibility is associated with this remediated vulnerability. No direct action is required from affected parties at this time.

Third Party Risk Assessment Platforms
General
Copy link
Many third-party organizations leverage “third-party risk assessment” platforms as part of their security due diligence efforts.
Unfortunately, the Palantir Information Security Team has increasingly observed that many of the platforms in this space are unreliable and include flawed “results” or “findings” which are irrelevant and erroneous. These platforms regularly misattribute information between unrelated organizations, employ questionable techniques resulting in data collection and completeness problems, and fundamentally do not provide valuable information about Palantir’s infrastructure or security risk.
At the date of this publication, historic substantive, true-positive findings observed in these platforms has been de minimus. Individually responding to erroneous findings across an increasing tapestry of vendors in this space is an onerous and expensive task which ultimately detracts from meaningful cybersecurity work. As such, it is the policy of the Palantir information security team not to respond to inquiries or “findings” generated by such vendors or platforms.
We believe this policy allows us to best direct our cybersecurity resources towards efforts that maximize the security for Palantir, and for our customers. This ultimately allows us to meet the highest bar for security, data protection, privacy, and compliance, to which we are committed. In furtherance of this commitment, through our Safebase portal, we have published detailed security documentation, including reliable information reflecting risk and posture management, penetration and security testing, our accreditations, security controls, and other relevant, and detailed, security and technical information in order to inform meaningful risk assessments by our customers and prospective customers.
We remain confident that these materials demonstrate how Palantir’s infrastructure and operations meet the highest security standards.

Security Bulletin
A security bulletin has been publicly disclosed for our software.
PALSEC-2022-05
The delivery-metadata service in Palantir Apollo was found to permit API endpoints that did not adequately require authentication to query, potentially granting read access to metadata such as deployed software version numbers to unintended recipients. The subsequent investigation uncovered insufficient authentication controls in the team-ownership service as well, which is responsible for metadata pertaining to package installations. These vulnerabilities are resolved in apollo-deployment-state version 4.714.0, delivery-metadata version 2.565.0, and team-ownership version 0.171.0, respectively. As part of maintaining good security hygiene, it is highly recommended that all customers upgrade to the latest version of all relevant Apollo services.

Security Response******CVE-2022-3786 and CVE-2022-3602:******Background
On October 25th, the OpenSSL maintainers published an announcement to the community of a forthcoming release of version 3.0.7 which contained a patch for a CRITICAL vulnerability set to be released on November 1. Upon receiving the notification, the Palantir CIRT (Computer Incident Response Team) opened an investigation to determine the overall exposure to Palantir platforms and infrastructure. Subsequent notices from the OpenSSL maintainers indicated that only the 3.0.x branch contained the CRITICAL fix and so, in conjunction with our product development teams, we began to investigate and understand the usage of OpenSSL 3.0.x across our organization. By Friday October 28th we concluded our assessment and stood by for the November 1 release.
Yesterday, OpenSSL 3.0.7 was released which resolved two HIGH CVEs: CVE-2022-3786 and CVE-2022-3602. After the initial announcement on October 25th, the OpenSSL maintainers conducted further analysis of the issues and determined they were not as exploitable as initially thought. Regardless, the Palantir InfoSec Team treats all software issues of this nature with the utmost importance, regardless of the surrounding circumstances.
Palantir is not affected
Palantir is not affected by the OpenSSL vulnerabilities in CVE-2022-3786 and CVE-2022-3602:
After a comprehensive search for usage of the offending libraries we have no reliance on and have found no evidence of OpenSSL 3.0.x in our hosted infrastructure and products. There is no action required for any of our customers.

gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Ubuntu Security Notice 5710-1 - It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext.
