This Metasploit module uses a malformed packet or timing attack to enumerate users on an OpenSSH server. The default action sends a malformed (corrupted) SSH_MSG_USERAUTH_REQUEST packet using public key authentication (must be enabled) to enumerate users. On some versions of OpenSSH under some configurations, OpenSSH will return a "permission denied" error for an invalid user faster than for a valid user, creating an opportunity for a timing attack to enumerate users. Testing note: invalid users were logged, while valid users were not. YMMV.
An Improper Privilege Management vulnerability in SUSE Rancher allowed standard users to leverage their existing permissions to manipulate Kubernetes secrets in the local cluster, resulting in the secret being deleted, but their read-level permissions to the secret being preserved. When this operation was followed-up by other specially crafted commands, it could result in the user gaining access to tokens belonging to service accounts in the local cluster. This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.
CheckMK Raw Edition software (versions 1.5.0 to 1.6.0) does not sanitise the input of a web service parameter that is in an unauthenticated zone. This Reflected XSS allows an attacker to open a backdoor on the device with HTML content and interpreted by the browser (such as JavaScript or other client-side scripts) or to steal the session cookies of a user who has previously authenticated via a man in the middle. Successful exploitation requires access to the web service resource without authentication.

# Description The export feature lets a user export a single entry or a set of entries in a given format (_e.g. PDF, MOBI, TXT_). For example, `https://yourinstance.wallabag.org/export/45.pdf` will export the entry with id 45 in PDF format. Since wallabag 2.0.0-alpha.1, this feature is vulnerable to an insecure direct object reference attack. A logged user can export any single entry without ownership validation. This is due to a lack of access validation in the `downloadEntryAction` method. **You should immediately patch your instance to version 2.5.3 or higher if you have more than one user and/or having open registration.** # Resolution A user check is now done in the vulnerable method before sending the exported entry. The `Entry` retrieval through a `ParamConverter` has also been replaced with a call to the `EntryRepository` in order to prevent any information disclosure through response discrepancy. # Workaround If you are unable to update to the latest version or if yo...
### Summary This is a comment on https://github.com/NaturalIntelligence/fast-xml-parser/security/advisories/GHSA-6w63-h3fj-q4vw and the patches fixing it. ### Details The code which validates a name calls the validator: https://github.com/NaturalIntelligence/fast-xml-parser/blob/ecf6016f9b48aec1a921e673158be0773d07283e/src/xmlparser/DocTypeReader.js#L145-L153 This checks for the presence of an invalid character. Such an approach is always risky, as it is so easy to forget to include an invalid character in the list. A safer approach is to validate entity names against the XML specification: https://www.w3.org/TR/xml11/#sec-common-syn - an ENTITY name is a Name: ``` [4] NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] [4a] NameChar ::= N...
### Issue Snowflake discovered and remediated a vulnerability in the Snowflake NodeJS Driver. File permissions checks of the temporary credential cache could be bypassed by an attacker with write access to the local cache directory. This vulnerability affects versions 1.12.0 through 2.0.1 on Linux. Snowflake fixed the issue in version 2.0.2. ### Vulnerability Details On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake NodeJS Driver will cache temporary credentials in a local file. Due to a bug, the check verifying that the cache file can be accessed only by the user running the Driver always succeeded, but didn’t verify the permissions or the ownership correctly. An attacker with write access to the local cache folder could plant an empty file there and the Driver would use it to store temporary credentials instead of rejecting it due to overly broad permissions. ### Solution Snowflak...
### Summary In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error. ### Details A flaw in the authentication check process allows an attacker to specify any arbitrary username that does not exist on the system, along with a salted hash of an empty password. Under these conditions, Navidrome treats the request as authenticated, granting access to various Subsonic endpoints without requiring valid credentials. ### Proof of Concept (PoC) 1. Generate a random salt: ```javascript // e.g., salt = "x1vbudn1m6d" Math.random().toString(36).substring(2, 15) ``` 2. Calculate the MD5 hash of an empty password plus the salt: ```shell # Using the example salt above echo -n "x1vbudn1m6d" | md5sum 81f0c0fb5d202ab0d012e6eaeb722d79 - ``` 3. Send a re...
