Attack-Flow Graph

Executive Summary

This vulnerability involves missing permission checks in Jenkins versions 2.567 and earlier, including LTS 2.555.2 and earlier. It allows attackers who have Overall/Read permission to discover other users' configured timezones and to enumerate the names of views in other users' "My Views" sections.

Impact Analysis

The impact of this vulnerability is that an attacker with limited read permissions can gain information about other users' settings, such as their timezone and view names. While this does not directly allow modification or control, it can lead to information disclosure and potentially aid in further targeted attacks or reconnaissance within the Jenkins environment.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Jenkins to a version later than 2.567 or LTS later than 2.555.2, where the issue has been addressed.

Since the vulnerability allows attackers with Overall/Read permission to enumerate user timezones and view names, restricting such permissions to trusted users can reduce risk.
