CVE-2023-35143
Published: 14 June 2023
Summary
CVE-2023-35143 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Maven Repository Server. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 8.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins Maven Repository Server Plugin 1.10 and earlier contains a stored cross-site scripting vulnerability because it fails to escape build artifact versions displayed on the Build Artifacts As Maven Repository page. The affected component is the Jenkins plugin that renders Maven repository views from project build data.
Attackers who can control Maven project versions inside a pom.xml file can inject arbitrary script content that executes in the browsers of other users who view the affected page. Successful exploitation allows the attacker to perform actions as the victim user within the Jenkins instance, with impact limited to confidentiality and integrity exposure under the reported CVSS vector.
The Jenkins security advisory SECURITY-3156 and the associated OpenWall disclosure provide the official details and recommended actions for this issue. The EPSS score has remained flat at 0.0756 with no material increase after disclosure.
