The vulnerability identified as CVE-2023-4301 represents a critical cross-site request forgery flaw within the Jenkins Fortify Plugin version 22.1.38 and earlier. This weakness stems from insufficient validation of request origins and lacks proper anti-CSRF token implementation in the plugin's web interface. The vulnerability allows malicious actors to craft forged requests that can interact with the Jenkins server using credentials stored within the system, effectively enabling unauthorized access to sensitive resources and data.
The technical exploitation of this CSRF vulnerability occurs when an attacker crafts a malicious web page or request that, when visited by an authenticated Jenkins user, automatically performs actions on the user's behalf without their knowledge or consent. The Fortify Plugin's failure to implement robust CSRF protection mechanisms means that attackers can leverage stolen or obtained credential IDs to execute unauthorized operations against the Jenkins instance. This flaw specifically targets the plugin's handling of credential management and authentication flows, creating a pathway for credential theft and unauthorized system access.
The operational impact of CVE-2023-4301 extends beyond simple credential theft, as it enables attackers to potentially escalate privileges and access sensitive configuration data within Jenkins. The vulnerability creates a persistent threat vector that can be exploited repeatedly, as long as the attacker can maintain access to the victim's browser session or can trick users into visiting malicious pages. Organizations using Jenkins with the affected Fortify Plugin face significant risk of unauthorized code deployments, configuration changes, and potential data breaches. The vulnerability aligns with CWE-352, which specifically addresses cross-site request forgery weaknesses, and can be mapped to ATT&CK technique T1566.001 for credential access through social engineering.
Mitigation strategies for this vulnerability require immediate patching of the Jenkins Fortify Plugin to version 22.1.39 or later, which contains the necessary CSRF protection fixes. Organizations should also implement additional security controls including network segmentation, web application firewalls, and enhanced monitoring of Jenkins access patterns. Regular security audits of Jenkins plugins and configurations are essential to prevent similar vulnerabilities from emerging. The fix typically involves implementing proper CSRF token validation, origin checking, and ensuring that all state-changing operations require explicit user confirmation through anti-CSRF mechanisms. Security teams should also consider implementing just-in-time credential rotation and access control policies to minimize the impact of any potential exploitation attempts.
