CVE-2023-28678
Published: 02 April 2023
Summary
CVE-2023-28678 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Cppcheck. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 7.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a stored cross-site scripting flaw (CWE-79) affecting the Jenkins Cppcheck Plugin in versions 1.26 and earlier. The plugin fails to escape file names extracted from Cppcheck report files before rendering them in the Jenkins UI, allowing untrusted content to be displayed without proper sanitization. It carries a CVSS 3.1 score of 5.4.
Attackers able to control the contents of Cppcheck report files can supply malicious payloads in file names that execute when other users view the reports in Jenkins. Successful exploitation permits stored XSS attacks that can lead to limited impacts on confidentiality and integrity within the Jenkins instance, requiring low privileges and some user interaction.
The Jenkins security advisory published on March 21, 2023, addresses the issue under SECURITY-2809 and directs users to apply the available plugin update that resolves the lack of escaping. The current EPSS score of 0.0898, following a modest peak of 0.1119, indicates limited observed exploitation interest.
