CVE-2020-2139Network attack vector

Arbitrary file overwrite via unsanitized XML paths

Published Mar 9, 2020 · Updated Aug 4, 2024

An arbitrary file write in Jenkins Cobertura Plugin 1.15 and earlier allows remote authenticated users to overwrite files via crafted coverage XML. The plugin parses file paths from the coverage report XML without validating that they remain under the configured base directory. Exploitation requires permission to control the Publish Cobertura Coverage Report input, and the consequence is integrity loss on the Jenkins controller filesystem.
