Description Preview
Overview
The Jenkins FitNesse Plugin is used to integrate FitNesse testing framework with Jenkins. The vulnerability exists because the plugin does not properly configure its XML parser to disable external entity resolution. When processing XML data, the plugin may resolve and include external entities referenced in the XML document, which can lead to information disclosure, server-side request forgery, or denial of service attacks. An attacker with the ability to control XML input processed by the plugin could exploit this vulnerability to access sensitive information or disrupt the service.
Remediation
Users should update to Jenkins FitNesse Plugin version 1.31 or later, which properly configures the XML parser to prevent XXE attacks. If updating is not immediately possible, consider implementing the following temporary mitigations:
- Restrict access to Jenkins and the FitNesse Plugin to trusted users only
- Monitor system logs for suspicious XML processing activities
- Consider implementing network-level controls to prevent outbound connections from the Jenkins server that could be used in XXE attacks
