Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in the Jenkins SonarQube Scanner Plugin versions 2.18.3 and earlier. It occurs because the plugin does not restrict URL schemes in dashboard links generated from SonarQube scanner results, allowing the use of the javascript: scheme. Attackers with Item/Configure permission can exploit this to inject malicious scripts.

Impact Analysis

An attacker with Item/Configure permission could inject malicious JavaScript code via a crafted SonarQube scanner result. This could lead to unauthorized actions being performed on behalf of users, theft of session cookies, or defacement of the Jenkins interface. Users with access to affected dashboards may have their sessions compromised.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, potentially violating GDPR's data protection requirements or HIPAA's security rules for protected health information. Organizations may face compliance penalties if user data is exposed due to this XSS flaw.

Mitigation Strategies

Update Jenkins SonarQube Scanner Plugin to version 2.18.4 or later to address the stored XSS vulnerability.
