Description Preview

A vulnerability in Jenkins before versions 2.44 and 2.32.2 allows low privilege users to act on administrative monitors due to insufficient permission checks. This security issue is tracked as SECURITY-371 and is classified as an improper authentication vulnerability (CWE-287).

Overview

Jenkins administrative monitors are components that provide notifications about various system issues that require administrator attention. Due to inconsistent permission checks, low privilege users could interact with these administrative monitors, potentially allowing them to perform actions that should be restricted to administrators. This vulnerability could lead to privilege escalation within Jenkins instances, allowing users with limited access to perform administrative actions, potentially compromising the security and integrity of the Jenkins environment.

Remediation

To address this vulnerability, users should upgrade to Jenkins 2.44 or 2.32.2 or later versions, which include fixes for this issue. The patch implements consistent permission checks for all administrative monitor actions, ensuring that only users with appropriate administrative privileges can interact with these components.

For users who cannot immediately upgrade, it is recommended to review and restrict access to Jenkins, ensuring that only trusted users have accounts on the system. Additionally, monitor system logs for any suspicious activities that might indicate exploitation of this vulnerability.
