XXE vulnerability in Jenkins CVS Plugin

Source: GitHub Advisory Database (reviewed) High CVE-2020-2324

Packages

EcosystemPackageAffectedFixed in
Maven org.jenkins-ci.plugins:cvs < 2.17 2.17

Details

As written in the advisory (Markdown source, shown as plain text).

Jenkins CVS Plugin 2.16 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. Jenkins CVS Plugin 2.17 disables external entity resolution for its XML parser.
