Background
The ClearCase Release Plugin is a Maven package that integrates with Jenkins, a popular automation server. It allows users to manage and release composite baselines in ClearCase, a software configuration management system. The plugin provides functionality for creating and configuring jobs related to ClearCase releases. However, versions 0.3 and earlier of the plugin are vulnerable to a stored cross-site scripting (XSS) attack.
Vulnerability Detail
The stored XSS vulnerability in the ClearCase Release Plugin arises from the plugin's failure to properly escape the composite baseline in the badge tooltip. This allows attackers with Job/Configure permission to inject malicious scripts into the tooltip, which can then be executed by unsuspecting users who hover over the badge. The impact of this vulnerability can range from unauthorized data disclosure to the execution of arbitrary code in the context of the affected user's session. The vulnerability has been assigned a CVSS score of 8.0, indicating a high severity level.
