Jenkins SCM HttpClient Plugin vulnerable to Cross-Site Request Forgery

Moderate severity GitHub Reviewed Published Sep 22, 2022 to the GitHub Advisory Database • Updated Feb 2, 2023

Package

maven com.meowlomo.jenkins:scm-httpclient (Maven)

Affected versions

<= 1.5

Patched versions

None

Description

SCM HttpClient Plugin 1.5 and earlier does not perform permission check in a method implementing form validation.

This allows attackers with Overall/Read permission to connect to an attacker-specified HTTP server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Additionally, this form validation method does not require POST requests, resulting in a cross-site request forgery (CSRF) 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.
