Jenkins CloudBees CD Plugin vulnerable to arbitrary file read

Moderate severity GitHub Reviewed Published Oct 25, 2023 to the GitHub Advisory Database • Updated Nov 11, 2023

Package

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

Affected versions

< 1.1.33

Patched versions

1.1.33

Description

Jenkins CloudBees CD Plugin temporarily copies files from an agent workspace to the controller in preparation for publishing them in the 'CloudBees CD - Publish Artifact' post-build step.

CloudBees CD Plugin 1.1.32 and earlier follows symbolic links to locations outside of the temporary directory on the controller when collecting the list of files to publish.

This allows attackers able to configure jobs to publish arbitrary files from the Jenkins controller file system to the previously configured CloudBees CD server.

CloudBees CD Plugin 1.1.33 ensures that only files located within the expected directory are published.

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.
