Jenkins Pipeline Utility Steps Plugin provides the untar and unzip Pipeline steps to extract archives into job workspaces. Pipeline Utility Steps Plugin 2.15.2 and earlier does not validate or limit file paths of files contained within these archives. This allows attackers able to provide crafted archives as parameters to create or replace arbitrary files on the agent file system with attacker-specified content. Pipeline Utility Steps Plugin 2.15.3 rejects extraction of files in tar and zip archives that would be placed outside the expected destination directory.
Recommended action: Upgrade to 2.15.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
Pipeline Utility Steps Plugin implements a readProperties Pipeline step that supports interpolation of variables using the Apache Commons Configuration library. Pipeline Utility Steps Plugin 2.13.1 and earlier does not restrict the set of enabled prefix interpolators and bundles versions of this library that enable the file: prefix interpolator by default. This allows attackers able to configure Pipelines to read arbitrary files from the Jenkins controller file system. Pipeline Utility Steps Plugin 2.13.2 restricts the set of prefix interpolators enabled by default to base64Decoder:, base64Encoder:, date:, urlDecoder:, and urlEncoder:. Administrators can set the Java system property org.jenkinsci.plugins.pipeline.utility.steps.conf.ReadPropertiesStepExecution.CUSTOMPREFIXINTERPOLATORLOOKUPS to customize which prefix interpolators are enabled.
