Executive Summary

Jenkins Summary Display Plugin 1.15 and earlier has a stored cross-site scripting (XSS) vulnerability. The issue occurs because the plugin does not properly escape job names in a JavaScript context on build report pages. Attackers with Item/Create or Item/Configure permissions can exploit this to inject malicious scripts.

Detection Guidance

This vulnerability can be detected by checking the installed version of the Jenkins Summary Display Plugin. If the version is 1.15 or earlier, the system is vulnerable. Use the Jenkins script console or CLI to run: 'println(Jenkins.instance.pluginManager.plugins.findAll { it.shortName == "summary-display" }.version)' to check the version.

Impact Analysis

This vulnerability allows attackers with specific permissions to inject and execute malicious scripts in the context of a user's browser session. This could lead to unauthorized actions, data theft, or session hijacking for users viewing affected build reports.

Compliance Impact

This XSS vulnerability could compromise user data confidentiality, potentially violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations may face compliance violations if user data is exposed due to this flaw.

Mitigation Strategies

Immediately update the Jenkins Summary Display Plugin to the latest version. If updating is not possible, disable or uninstall the plugin until a patch is available. Restrict Item/Create and Item/Configure permissions to trusted users only.
