The CVE-2025-XXXX vulnerability exists within the Jenkins Start Windocks Containers Plugin, version 1.4 and earlier. The plugin fails to perform any permission checks on a specific HTTP endpoint. This means that any user with the Overall/Read permission in Jenkins, which is a basic and commonly assigned privilege, can interact with this endpoint. The endpoint allows for connecting to a user-specified URL. Because there is no authorization validation, an attacker can exploit this to force the Jenkins instance to connect to a malicious server under their control. Furthermore, this vulnerable endpoint does not require POST requests, making it susceptible to Cross-Site Request Forgery (CSRF). An attacker could trick a logged-in administrator into visiting a webpage that sends a forged GET request to this endpoint, triggering the unauthorized connection without the admin’s knowledge.
Platform: Jenkins Plugin
Version: <=1.4
Vulnerability: Missing Authorization
Severity: Moderate
date: 2024-10-29
Prediction: 2024-11-19
What Undercode Say:
`curl -X GET ‘http://jenkins-host/plugin/start-windocks/endpoint?url=http://attacker-server’`
` No permission check performed on the server-side for this request.`
` CSRF PoC: `
How Exploit:
Attackers with read access can connect Jenkins to an attacker-controlled server. CSRF attacks can be launched via a malicious site visited by an authenticated user.
Protection from this CVE:
No patch available. Restrict plugin usage or apply network controls.
Impact:
Information disclosure, potential server-side request forgery (SSRF), unauthorized system interaction.
