CSRF vulnerability in Jenkins promoted builds Plugin

Moderate severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Dec 15, 2023

Package

maven org.jenkins-ci.plugins:promoted-builds (Maven)

Affected versions

<= 3.9

Patched versions

3.9.1

Description

Jenkins promoted builds Plugin 3.9 and earlier does not require POST requests for HTTP endpoints implementing promotion (regular, forced, and re-execute), resulting in cross-site request forgery (CSRF) vulnerabilities.

These vulnerabilities allow attackers to promote builds.

Jenkins promoted builds Plugin 3.9.1 requires POST requests for the affected HTTP endpoints.

A security hardening since Jenkins 2.287 and LTS 2.277.2 prevents exploitation of this vulnerability.

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.
