This Windows PowerShell Phish Has Scary Potential

Many GitHub users this week received a novel phishing email warning of critical security holes in their code. Those who clicked the link for details were asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware. While it's unlikely that many programmers fell for this scam, it's notable because less targeted versions of it are likely to be far more successful against the average Windows user.

GHSA-w69q-w4h4-2fx8: Reverb use after free vulnerability

There exists a use after free vulnerability in Reverb. Reverb supports the VARIANT datatype, which is supposed to represent an arbitrary object in C++. When a tensor proto of type VARIANT is unpacked, memory is first allocated to store the entire tensor, and a ctor is called on each instance. Afterwards, Reverb copies the content in tensor_content to the previously mentioned pre-allocated memory, which results in the bytes in tensor_content overwriting the vtable pointers of all the objects which were previously allocated. Reverb exposes 2 relevant gRPC endpoints: InsertStream and SampleStream. The attacker can insert this stream into the server’s database, then when the client next calls SampleStream they will unpack the tensor into RAM, and when any method on that object is called (including its destructor) the attacker gains control of the Program Counter. We recommend upgrading past git commit  https://github.com/google-deepmind/reverb/commit/6a0dcf4c9e842b7f999912f792aaa6f6bd261a2...

GHSA-vvf8-2h68-9475: Keycloak Open Redirect vulnerability

A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.

Talk of election security is good, but we still need more money to solve the problem

This year, Congress only allocated $55 million in federal grant dollars to states for security and other election improvements.

GHSA-84jw-g43v-8gjm: DOM Clobbering Gadget found in Rspack's AutoPublicPathRuntimeModule that leads to XSS

Hi, Rspack|Webpack developer team! ## Summary We discovered a DOM Clobbering vulnerability in Webpack’s AutoPublicPathRuntimeModule. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. We found the real-world exploitation of this gadget in the Canvas LMS which allows XSS attack happens through an javascript code compiled by Webpack (the vulnerable part is from Webpack). We believe this is a severe issue. If Webpack’s code is not resilient to DOM Clobbering attacks, it could lead to significant security vulnerabilities in any web application using Webpack-compiled code. ## Details ### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in t...

GHSA-jj94-6f5c-65r8: ZITADEL Allows Unauthorized Access After Organization or Project Deactivation

### Summary In Zitadel, even after an organization is deactivated, associated projects, respectively their applications remain active. Users across other organizations can still log in and access through these applications, leading to unauthorized access. Additionally, if a project was deactivated access to applications was also still possible. ### Details The issue stems from the fact that when an organization is deactivated in Zitadel, the applications associated with it do not automatically deactivate. The application lifecycle is not tightly coupled with the organization's lifecycle, leading to a situation where the organization or project is marked as inactive, but its resources remain accessible. ### PoC - Create a new Organization, create new project and setup OpenID connect. - Deactivate an Organization - Setup authentication without selecting Check for Project on Authentication - User is able to login despite the organization is deactivated ### Impact This vulnerability all...

GHSA-68j8-fp38-p48q: Gematik Referenzvalidator has an XXE vulnerability that can lead to a Server Side Request Forgery attack

### Impact The profile location routine in the referencevalidator commons package is vulnerable to [XML External Entities](https://owasp.org/www-project-top-ten/2017/A4_2017-XML_External_Entities_(XXE)) attack due to insecure defaults of the used Woodstox WstxInputFactory. A malicious XML resource can lead to network requests issued by referencevalidator and thus to a [Server Side Request Forgery](https://owasp.org/www-community/attacks/Server_Side_Request_Forgery) attack. The vulnerability impacts applications which use referencevalidator to process XML resources from untrusted sources. ### Patches The problem has been patched with the [2.5.1 version](https://github.com/gematik/app-referencevalidator/releases/tag/2.5.1) of the referencevalidator. Users are strongly recommended to update to this version or a more recent one. ### Workarounds A pre-processing or manual analysis of input XML resources on existence of DTD definitions or external entities can mitigate the problem. ###...

GHSA-c459-2m73-67hj: SOFA Hessian Remote Command Execution (RCE) Vulnerability

### Impact SOFA Hessian protocol uses a blacklist mechanism to restrict deserialization of potentially dangerous classes for security protection. But there is a gadget chain that can bypass the SOFA Hessian blacklist protection mechanism, and this gadget chain only relies on JDK and does not rely on any third-party components. ### Patches Fixed this issue by update blacklist, users can upgrade to sofahessian version 3.5.5 to avoid this issue. ### Workarounds You can maintain a blacklist yourself in this directory `external/serialize.blacklist`.

GHSA-62c8-mh53-4cqv: HTTP client can manipulate custom HTTP headers that are added by Traefik

### Impact There is a vulnerability in Traefik that allows the client to remove the X-Forwarded headers (except the header X-Forwarded-For). ### Patches - https://github.com/traefik/traefik/releases/tag/v2.11.9 - https://github.com/traefik/traefik/releases/tag/v3.1.3 ### Workarounds No workaround. ### For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues). <details> <summary>Original Description</summary> ### Summary When a HTTP request is processed by Traefik, certain HTTP headers such as X-Forwarded-Host or X-Forwarded-Port are added by Traefik before the request is routed to the application. For a HTTP client, it should not be possible to remove or modify these headers. Since the application trusts the value of these headers, security implications might arise, if they can be modified. For HTTP/1.1, however, it was found that some of theses custom headers can indeed be removed and in ...
