CVE-2020-2138: XEE
First published: Mon Mar 09 2020(Updated: )
Cobertura Plugin 1.15 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows a user able to control the input files for the 'Publish Cobertura Coverage Report' post-build step to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. Cobertura Plugin 1.16 disables external entity resolution for its XML parser.
