Bitbucket Server Integration Plugin allows bypassing CSRF protection for any URL

High severity GitHub Reviewed Published Jan 22, 2025 to the GitHub Advisory Database • Updated Jan 22, 2025

Package

maven io.jenkins.plugins:atlassian-bitbucket-server-integration (Maven)

Affected versions

>= 2.1.0, < 4.1.4

Patched versions

4.1.4

Description

An extension point in Jenkins allows selectively disabling cross-site request forgery (CSRF) protection for specific URLs. Bitbucket Server Integration Plugin implements this extension point to support OAuth 1.0 authentication.

In Bitbucket Server Integration Plugin 2.1.0 through 4.1.3 (both inclusive) this implementation is too permissive, allowing attackers to craft URLs that would bypass the CSRF protection of any target URL.

Bitbucket Server Integration Plugin 4.1.4 restricts which URLs it disables cross-site request forgery (CSRF) protection for to the URLs that needs it.

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.
