Path traversal in Jenkins build-publisher Plugin

Moderate severity GitHub Reviewed Published Sep 22, 2022 to the GitHub Advisory Database • Updated Jan 31, 2023

Package

maven org.jenkins-ci.plugins:build-publisher (Maven)

Affected versions

<= 1.22

Patched versions

None

Description

Jenkins Build-Publisher Plugin 1.22 and earlier allows attackers with Item/Configure permission to create or replace any config.xml file on the Jenkins controller file system by providing a crafted file name to an API endpoint. Additionally, this endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability that allows attackers to replace any config.xml file on the Jenkins controller file system with an empty file.

There is currently no known workaround or fix, and this plugin has been suspended.

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.
