Jenkins Pipeline Utility Steps Plugin arbitrary file write vulnerability

Moderate severity GitHub Reviewed Published May 16, 2023 to the GitHub Advisory Database • Updated Jan 4, 2024

Package

maven org.jenkins-ci.plugins:pipeline-utility-steps (Maven)

Affected versions

< 2.15.3

Patched versions

2.15.3

Description

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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
