This cross-site request forgery vulnerability in the Jenkins Coverity Plugin affects versions 1.11.4 and earlier, representing a critical security flaw that undermines the integrity of credential management within Jenkins environments. The vulnerability stems from insufficient validation of CSRF tokens in the plugin's web interface, allowing malicious actors to craft crafted requests that can execute unauthorized actions against the Jenkins server. Attackers can exploit this weakness to force the server into making requests to arbitrary URLs using stored credential IDs, effectively enabling credential theft and unauthorized access to connected systems.
The technical implementation of this vulnerability involves the plugin's failure to properly verify the authenticity of incoming requests through the absence of proper CSRF protection mechanisms. When users interact with the Coverity plugin interface, the system does not adequately validate that requests originate from legitimate sources within the same session, creating an attack surface where malicious actors can manipulate the application's behavior. This flaw specifically affects the plugin's ability to handle credential operations, allowing attackers to leverage stolen or previously obtained credential IDs to establish unauthorized connections to external systems, potentially compromising sensitive infrastructure.
The operational impact of this vulnerability extends beyond simple credential theft, as it enables attackers to perform actions within the Jenkins environment that could lead to further compromise of the build infrastructure. An attacker who successfully exploits this CSRF vulnerability can access and manipulate Jenkins credentials, potentially gaining access to source code repositories, deployment systems, and other connected services that rely on these stored credentials. The vulnerability's exploitation requires minimal user interaction beyond initial access to the Jenkins interface, making it particularly dangerous in environments where users maintain persistent sessions or where the plugin interface is accessible to untrusted parties. This weakness directly violates the principle of least privilege and undermines the security model of Jenkins credential storage.
Organizations should immediately upgrade to versions of the Coverity Plugin that address this CSRF vulnerability, as the patch typically includes proper CSRF token validation and session management controls. The mitigation strategy should also involve implementing additional security measures such as network segmentation, restricting access to Jenkins interfaces through firewalls, and employing multi-factor authentication for administrative access. Security teams should conduct comprehensive audits of all Jenkins plugins to identify similar CSRF vulnerabilities and ensure proper input validation across all web interfaces. This vulnerability aligns with CWE-352, which specifically addresses cross-site request forgery weaknesses, and represents a common attack pattern categorized under ATT&CK technique T1566 for credential access through exploitation of web application vulnerabilities. Regular security assessments and vulnerability scanning should be implemented to prevent similar issues in other Jenkins plugins and ensure the overall security posture remains intact.
