Agent-to-controller security bypass in Jenkins Semantic Versioning Plugin

Critical severity GitHub Reviewed Published Jan 26, 2023 to the GitHub Advisory Database • Updated Feb 6, 2023

Package

maven org.jenkins-ci.plugins:semantic-versioning-plugin (Maven)

Affected versions

< 1.15

Patched versions

1.15

Description

Jenkins Semantic Versioning Plugin 1.14 and earlier does not restrict execution of an controller/agent message to agents, and implements no limitations about the file path that can be parsed, allowing attackers able to control agent processes to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

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.
