Agent-to-controller security bypass in Jenkins xUnit Plugin

Moderate severity GitHub Reviewed Published Jun 24, 2022 to the GitHub Advisory Database • Updated Jan 31, 2023

Package

maven org.jenkins-ci.plugins:xunit (Maven)

Affected versions

< 3.1.0

Patched versions

3.1.0

Description

xUnit Plugin 3.0.8 and earlier implements an agent-to-controller message that creates a user-specified directory if it doesn’t exist, and parsing files inside it as test results.

This allows attackers able to control agent processes to create an arbitrary directory on the Jenkins controller or to obtain test results from existing files in an attacker-specified directory.

xUnit Plugin 3.1.0 changes the message type from agent-to-controller to controller-to-agent, preventing execution on the controller.

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.
