The vulnerability identified as CVE-2023-40345 affects the Jenkins Delphix Plugin version 3.0.2 and earlier, presenting a critical access control flaw that undermines the security posture of Jenkins environments relying on this plugin. This issue stems from improper credential context handling within the plugin's architecture, creating a privilege escalation vector that allows unauthorized users to extract sensitive authentication information. The vulnerability specifically targets environments where the Delphix plugin is used for database and data management operations, making it particularly concerning for organizations with extensive Jenkins-based CI/CD pipelines that depend on secure credential management.
The technical flaw manifests in the plugin's failure to properly enforce context boundaries when performing credential lookups, enabling attackers with minimal permissions to exploit the system's credential resolution mechanism. This misconfiguration allows unauthorized users to traverse the credential hierarchy and access authentication details that should be restricted to authorized personnel only. The vulnerability operates at the application level within Jenkins' security framework, specifically targeting the credential store's access controls and context validation mechanisms. According to CWE classification, this represents a weakness in the credential management system where insufficient access control validation permits unauthorized information disclosure.
The operational impact of this vulnerability extends beyond simple credential theft, as it enables attackers to potentially escalate their privileges and gain access to additional system resources. An attacker with Overall/Read permission can leverage this flaw to extract database credentials, API keys, and other sensitive authentication materials that may provide access to backend systems and databases. This capability significantly increases the attack surface for Jenkins environments and can lead to cascading security breaches within the organization's infrastructure. The vulnerability aligns with ATT&CK technique T1552.001 for "Credentials in Files" and T1078.004 for "Valid Accounts" as it enables unauthorized access to stored credentials and can facilitate further lateral movement within the network.
Organizations should immediately implement mitigation strategies including upgrading to Jenkins Delphix Plugin version 3.0.3 or later, which contains the necessary fixes for this credential context issue. Additionally, administrators should conduct thorough credential audits to identify any potential compromise, implement network segmentation to limit access to Jenkins environments, and review existing access controls to ensure proper least-privilege enforcement. The vulnerability demonstrates the critical importance of proper context handling in credential management systems and highlights the need for comprehensive security testing of third-party plugins within Jenkins environments. Security teams should also consider implementing monitoring solutions that can detect anomalous credential access patterns and establish incident response procedures specifically addressing credential theft scenarios.
