Executive Summary

This vulnerability exists in Jenkins versions 2.483 through 2.567 and LTS versions 2.492.1 through 2.555.2. It occurs because Jenkins does not properly escape the user-provided description of a generic offline cause that can be set via the POST config.xml API. This flaw results in a stored cross-site scripting (XSS) vulnerability.

Attackers who have Agent/Configure permission can exploit this vulnerability by injecting malicious scripts into the description field, which are then stored and executed in the context of users viewing that data.

Impact Analysis

The impact of this vulnerability is that an attacker with Agent/Configure permission can inject malicious scripts into Jenkins. These scripts can execute in the browsers of users who view the affected descriptions, potentially leading to unauthorized actions, data theft, or session hijacking.
