Stored XSS vulnerability in Jenkins Timestamper Plugin
CVE-2020-2137 · GHSA-6xxf-rwv4-mrjm
- Affected
- Maven org.jenkins-ci.plugins:timestamper <= 1.11.1
- Fixed in
- 1.11.2· Vendor fix available
- Issue
- Timestamper Plugin 1.11.1 and earlier does not escape or sanitize the HTML formatting used to display the timestamps in console output for builds. This results in a stored cross-site scripting vulnerability that can be exploited by users with Overall/Administer permission. Timestamper Plugin 1.11.2 sanitizes the HTML formatting for timestamps and only allows basic, safe HTML formatting.
Recommended action: Upgrade to 1.11.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
