CVE-2019-10282 in Klaros-Testmanagement Plugin
Summary
by MITRE
Jenkins Klaros-Testmanagement Plugin stores credentials unencrypted in job config.xml files on the Jenkins master where they can be viewed by users with Extended Read permission, or access to the master file system.

The vulnerability identified as CVE-2019-10282 affects the Jenkins Klaros-Testmanagement Plugin, presenting a significant security risk through improper credential handling practices. This flaw resides in how the plugin manages authentication information within Jenkins job configurations, creating an avenue for unauthorized access to sensitive data. The vulnerability specifically impacts environments where Jenkins is configured with multiple user roles and permission levels, particularly when users possess Extended Read permissions or direct access to the master file system. The issue demonstrates a fundamental failure in secure credential storage practices, where sensitive authentication data is persisted in plain text format rather than being properly encrypted or obfuscated.
The technical implementation of this vulnerability stems from the plugin's design decision to store credentials directly within the job configuration files without adequate protection mechanisms. When Jenkins processes job configurations, it serializes the plugin's credential information into the config.xml file, which is typically stored on the master node's file system. This approach violates established security principles for credential management and creates a persistent exposure point where any user with sufficient privileges can extract authentication details. The flaw represents a classic example of insecure data storage as classified under CWE-312, where sensitive data is stored in a manner that makes it accessible to unauthorized parties. The vulnerability is particularly concerning because it does not require elevated privileges beyond what is normally granted to users with Extended Read access, making it exploitable by individuals who should not have access to authentication credentials.
The operational impact of this vulnerability extends beyond simple credential theft, as it can enable attackers to escalate their privileges and gain access to additional systems or data within the Jenkins environment. When credentials are stored unencrypted in job configuration files, they become potential targets for both internal and external attackers who can leverage this information to compromise downstream systems or services that rely on the same authentication credentials. This vulnerability can facilitate lateral movement within an organization's infrastructure, as the stolen credentials may be used to access other systems where the same authentication details are employed. The risk is amplified when considering that Jenkins is often integrated with various CI/CD pipelines and automated deployment systems, where compromised credentials can lead to unauthorized code deployments or system modifications. According to ATT&CK framework category T1552, this vulnerability directly enables credential access techniques that can be used for privilege escalation and persistent access to target systems.
Mitigation strategies for this vulnerability should focus on immediate remediation through plugin updates and implementation of proper credential management practices. Organizations should prioritize updating to the latest version of the Klaros-Testmanagement Plugin where the vulnerability has been addressed through proper encryption or obfuscation of credential data. Additionally, administrators should implement strict access controls and privilege separation to minimize the risk of unauthorized access to Jenkins master file systems. The recommended approach includes configuring Jenkins with minimal required permissions, implementing role-based access controls, and establishing regular audits of job configurations to identify and remediate similar issues. Security best practices dictate that credential information should never be stored in plain text within configuration files, and organizations should implement centralized credential management solutions that provide secure storage and retrieval mechanisms. The vulnerability also highlights the importance of regular security assessments and penetration testing of Jenkins environments to identify similar issues in other plugins or configurations that may pose similar risks to credential security and overall system integrity.
