CVE-2025-31724 in Cadence vManager Plugin
Summary
by MITRE • 04/02/2025
Jenkins Cadence vManager Plugin 4.0.0-282.v5096a_c2db_275 and earlier stores Verisium Manager vAPI keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Extended Read permission, or access to the Jenkins controller file system.

The vulnerability identified as CVE-2025-31724 affects the Jenkins Cadence vManager Plugin version 4.0.0-282.v5096a_c2db_275 and earlier, presenting a critical security risk through improper credential handling. This flaw allows sensitive authentication tokens to be stored in plain text within job configuration files, creating an exploitable vector for unauthorized access to Verisium Manager vAPI services. The vulnerability stems from the plugin's failure to implement proper encryption or obfuscation mechanisms for storing API keys, which are essential for maintaining the security posture of integrated DevOps environments. The issue directly violates security best practices for credential management and represents a significant weakness in Jenkins' access control mechanisms.
The technical implementation of this vulnerability involves the plugin's storage mechanism where Verisium Manager vAPI keys are serialized directly into the job config.xml files without any form of encryption or tokenization. When Jenkins processes jobs that utilize the Cadence vManager plugin, it persists these credentials in the clear within the controller's file system, making them accessible through multiple attack vectors. Users with Extended Read permission can directly access these configuration files through Jenkins' web interface, while those with file system access to the Jenkins controller can read the credentials directly from the file system. This design flaw creates a persistent exposure that remains active until the configuration files are manually modified or the plugin is upgraded to a secure version.
The operational impact of this vulnerability extends beyond immediate credential theft, as it enables attackers to gain unauthorized access to Verisium Manager services that may control critical infrastructure components. The exposure of API keys can lead to unauthorized automation, data exfiltration, service disruption, and potential lateral movement within the organization's infrastructure. Attackers can leverage these stolen credentials to perform actions such as creating or modifying workflows, accessing sensitive data, or manipulating the automation pipeline. The vulnerability affects the principle of least privilege and undermines the security boundaries that Jenkins typically maintains between different user roles and system components, potentially allowing privilege escalation through credential reuse across multiple systems.
Security mitigations for this vulnerability should focus on immediate remediation through plugin version upgrades to address the unencrypted credential storage issue. Organizations must implement comprehensive credential rotation procedures for all affected systems and establish monitoring mechanisms to detect unauthorized access attempts. The recommended approach includes configuring Jenkins with proper access controls to limit Extended Read permissions to only trusted administrators, implementing file system access restrictions, and establishing automated credential management processes that do not rely on persistent storage of sensitive tokens. This vulnerability aligns with CWE-312 (Sensitive Data Exposure) and represents a violation of the principle of least privilege, with potential ATT&CK techniques including credential access through file system access and privilege escalation through stolen credentials. Organizations should also consider implementing additional security controls such as just-in-time credential provisioning, token-based authentication, and regular security audits of Jenkins configurations to prevent similar exposure scenarios.
