Jenkins Subversion Plugin Cross-Site Request Forgery vulnerability

Moderate severity GitHub Reviewed Published May 17, 2022 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

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

Affected versions

< 2.9

Patched versions

2.9

Description

Subversion Plugin connects to a user-specified Subversion repository as part of form validation (e.g. to retrieve a list of tags). This functionality improperly checked permissions, allowing any user with Item/Build permission (but not Item/Configure) to connect to any web server or Subversion server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery attacks. As of version 2.9, this functionality properly checks permissions and is only available via POST.

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.
