Jenkins Deployer Framework Plugin vulnerable to Path Traversal

Moderate severity GitHub Reviewed Published Jul 28, 2022 to the GitHub Advisory Database • Updated Nov 5, 2023

Package

maven org.jenkins-ci.plugins:deployer-framework (Maven)

Affected versions

<= 85.v1d1888e8c021

Patched versions

86.v7b_a_4a_55b_f3ec

Description

Jenkins Deployer Framework Plugin 85.v1d1888e8c021 and earlier does not restrict the name of files in methods implementing form validation.

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

Deployer Framework Plugin 86.v7b_a_4a_55b_f3ec ensures that only files contained inside the expected 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.

Weaknesses

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
