Jenkins Sidebar Link Plugin vulnerable to Path Traversal

Moderate severity GitHub Reviewed Published May 16, 2023 to the GitHub Advisory Database • Updated Jan 5, 2024

Package

maven org.jenkins-ci.plugins:sidebar-link (Maven)

Affected versions

< 2.2.2

Patched versions

2.2.2

Description

Jenkins Sidebar Link Plugin allows specifying files in the userContent/ directory for use as link icons.

Sidebar Link Plugin 2.2.1 and earlier does not restrict the path of files in a method implementing form validation.

This allows attackers with Overall/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.

Sidebar Link Plugin 2.2.2 ensures that only files located within the expected userContent/ directory can be accessed.

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.
