Complete lack of CSRF protection in Jenkins Selenium Plugin can lead to OS command injection

High severity GitHub Reviewed Published May 24, 2022 to the GitHub Advisory Database • Updated Jan 29, 2023

Package

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

Affected versions

<= 3.141.59

Patched versions

None

Description

Selenium Plugin 3.141.59 and earlier has no CSRF protection for its HTTP endpoints.

This allows attackers to perform the following actions:

  • Restart the Selenium Grid hub.
  • Delete or replace the plugin configuration.
  • Start, stop, or restart Selenium configurations on specific nodes.

Through carefully chosen configuration parameters, these actions can result in OS command injection on the Jenkins controller.

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.
