CVE-2020-2179

RCE vulnerability in Jenkins Yaml Axis Plugin

Impact

Yaml Axis Plugin 0.2.0 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to configure a multi-configuration (Matrix) job, or control the contents of a previously configured job’s SCM repository. Yaml Axis Plugin 0.2.1 configures its YAML parser to only instantiate safe types.
