Arbitrary file read vulnerability in Jenkins Pipeline Utility Steps Plugin

High severity GitHub Reviewed Published Nov 16, 2022 to the GitHub Advisory Database • Updated Jan 4, 2024

Package

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

Affected versions

<= 2.13.1

Patched versions

2.13.2

Description

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.CUSTOM_PREFIX_INTERPOLATOR_LOOKUPS to customize which prefix interpolators are enabled.

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.
