CVE-2023-43500
Jenkins Build Failure Analyzer Plugin Cross-Site Request Forgery vulnerability
Description
Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier does not perform a permission check in a connection test HTTP endpoint. This allows attackers with Overall/Read permission to connect to an attacker-specified hostname and port using attacker-specified username and password. Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. Build Failure Analyzer Plugin 2.4.2 requires POST requests and Overall/Administer permission for the affected HTTP endpoint.
