#vulnerability

Among the top exploited zero-day vulnerabilities were bugs found in systems from Citrix and Cisco.

Jenkins Shared Library Version Override Plugin 17.v786074c9fce7 and earlier declares folder-scoped library overrides as trusted, so that they're not executed in the Script Security sandbox, allowing attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection. This allows attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection. Shared Library Version Override Plugin 19.v3a_c975738d4a_ declares folder-scoped library overrides as untrusted, so that they’re executed in the Script Security sandbox.

Jenkins Authorize Project Plugin 1.7.2 and earlier evaluates a string containing the job name with JavaScript on the Authorization view, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission. Authorize Project Plugin 1.8.0 no longer evaluates a string containing the job name with JavaScript on the Authorization view.

Jenkins OpenId Connect Authentication Plugin 4.418.vccc7061f5b_6d and earlier does not invalidate the previous session on login. This allows attackers to use social engineering techniques to gain administrator access to Jenkins. OpenId Connect Authentication Plugin 4.421.v5422614eb_e0a_ invalidates the existing session on login.

The tech giant fixed privilege-escalation and model-exfiltration vulnerabilities in Vertex AI that could have allowed attackers to steal or poison custom-built AI models.

### Impact Deserialization of untrusted data from the `mimes` parameter could lead to remote code execution. ### Patches Fixed in 3.0.9 ### Workarounds Not needed, a `composer update` will solve it in a non-breaking way. ### References Reported responsibly Vladislav Gladkiy at [Positive Technologies](https://www.ptsecurity.com/ww-en/).

### Summary A vulnerability exists in the Create User process, allowing the creation of a new admin account with an option to upload a profile image. An attacker can upload a malicious SVG file containing an embedded script. When the profile image is accessed, the embedded script executes, leading to the potential theft of session cookies. ### Details 1. Login as admin 2. Go to Create User 3. Fill up everything in the registration form then upload SVG image as a profile picture 4. In SVG image, add script tag to prepare for XSS attack 5. Complete the Create User process 6. Right click at the image to obtain image URL address 7. XSS triggered ### PoC The below link is a private YouTube video for PoC. https://youtu.be/5j8owD0--1A ### Impact The stored XSS can lead to session hijacking and privilege escalation, effectively bypassing any CSRF protections in place.

### Description Whan consuming a persisted remember-me cookie, symfony does not check if the username persisted in the database matches the username attached with the cookie, leading to authentication bypass. ### Resolution The `PersistentRememberMeHandler` class now ensures the submitted username is the cookie owner. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/81354d392c5f0b7a52bcbd729d6f82501e94135a) for branch 5.4. ### Credits We would like to thank Moritz Rauch - Pentryx AG for reporting the issue and Jérémy Derussé for providing the fix.
