The cross-site request forgery vulnerability identified as CVE-2023-37955 affects the Jenkins Test Results Aggregator Plugin version 1.2.13 and earlier, representing a critical security flaw that undermines the integrity of web applications relying on Jenkins for continuous integration and delivery processes. This vulnerability falls under the Common Weakness Enumeration category CWE-352, which specifically addresses cross-site request forgery flaws in web applications. The issue manifests when the plugin fails to properly validate and authenticate requests originating from external sources, creating an attack vector where malicious actors can manipulate the application's behavior through crafted requests.
The technical implementation of this CSRF vulnerability stems from insufficient validation mechanisms within the plugin's request processing logic. When users interact with the Jenkins Test Results Aggregator Plugin, the system should verify that requests originate from legitimate sources and contain proper authentication tokens. However, the vulnerability allows attackers to construct malicious requests that can force the application to perform actions using attacker-specified credentials against a designated target URL. This flaw particularly affects environments where Jenkins is integrated with automated testing frameworks and continuous integration pipelines, where the aggregation of test results is a critical function.
The operational impact of this vulnerability extends beyond simple data manipulation, as it enables attackers to potentially compromise the entire testing and deployment pipeline. An attacker could leverage this vulnerability to redirect test result aggregations to malicious endpoints, potentially leading to data exfiltration or the injection of false test results that could bypass quality gates in software delivery processes. The vulnerability's exploitation could result in unauthorized access to sensitive testing data, manipulation of build statuses, and potential disruption of continuous integration workflows. Organizations relying on Jenkins for automated testing and deployment may face significant operational risks including compromised software quality assurance processes and potential security breaches in their development environments.
Mitigation strategies for CVE-2023-37955 should prioritize immediate plugin updates to versions that address the CSRF validation weaknesses, as recommended by the Jenkins security team. Organizations should also implement additional security controls including the enforcement of proper anti-CSRF tokens in all plugin interactions, regular security audits of Jenkins configurations, and network-level restrictions on plugin access. The vulnerability's characteristics align with ATT&CK technique T1566.001, which covers credential harvesting through phishing, as attackers could potentially use this vulnerability to manipulate authentication flows within Jenkins environments. Security teams should also consider implementing web application firewalls and monitoring for suspicious request patterns that could indicate CSRF attack attempts, while ensuring that all Jenkins plugins undergo regular security assessments to prevent similar vulnerabilities from emerging in other components of the continuous integration infrastructure.
