Jenkins LTS < 2.492.3 / Jenkins weekly < 2.504 Multiple Vulnerabilities

medium Nessus Plugin ID 233779

Language:

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 2.492.3 or Jenkins weekly prior to 2.504. It is, therefore, affected by multiple vulnerabilities:

 - A missing permission check in Jenkins 2.503 and earlier, LTS 2.492.2 and earlier allows attackers with Computer/Create permission but without Computer/Configure permission to copy an agent, gaining access to encrypted secrets in its configuration. (CVE-2025-31721)

 - A missing permission check in Jenkins 2.503 and earlier, LTS 2.492.2 and earlier allows attackers with Computer/Create permission but without Computer/Extended Read permission to copy an agent, gaining access to its configuration. (CVE-2025-31720)

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 2.504 or later, or Jenkins LTS to version 2.492.3 or later.
