Jenkins LTS < 2.528.3 / Jenkins weekly < 2.541 Multiple Vulnerabilities

medium Nessus Plugin ID 278129

Synopsis

An application running on a remote web server host is affected by multiple vulnerabilities

Description

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.528.3 or Jenkins weekly prior to 2.541. It is, therefore, affected by multiple vulnerabilities:

- A cross-site request forgery (CSRF) vulnerability in Jenkins 2.540 and earlier, LTS 2.528.2 and earlier allows attackers to trick users into logging in to the attacker's account. (CVE-2025-67639)

- Jenkins 2.540 and earlier, LTS 2.528.2 and earlier does not mask build authorization tokens displayed on the job configuration form, increasing the potential for attackers to observe and capture them.
(CVE-2025-67638)

- Jenkins 2.540 and earlier, LTS 2.528.2 and earlier does not properly close HTTP-based CLI connections when the connection stream becomes corrupted, allowing unauthenticated attackers to cause a denial of service.
(CVE-2025-67635)

- Jenkins 2.540 and earlier, LTS 2.528.2 and earlier stores build authorization tokens unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system. (CVE-2025-67637)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade Jenkins weekly to version 2.541 or later, or Jenkins LTS to version 2.528.3 or later.
