CVE-2019-16543 in Spira Importer Plugin
Summary
by MITRE
Jenkins Spira Importer Plugin 3.2.2 and earlier stores credentials unencrypted in its global configuration file on the Jenkins master where they can be viewed by users with access to the master file system.

The vulnerability identified as CVE-2019-16543 affects the Jenkins Spira Importer Plugin version 3.2.2 and earlier, presenting a critical security flaw in how credentials are managed within the Jenkins ecosystem. This issue stems from the plugin's improper handling of sensitive authentication data, which are stored in plain text format within the global configuration file of the Jenkins master server. The flaw represents a fundamental failure in secure credential management practices, as it violates established security principles that require all sensitive data to be encrypted both at rest and in transit. The vulnerability directly impacts the confidentiality aspect of the CIA triad, as unauthorized users with file system access to the Jenkins master can easily extract and utilize these stored credentials for malicious purposes.
The technical implementation of this flaw involves the plugin's configuration storage mechanism which fails to apply encryption to credential fields during the serialization process into the global configuration file. This unencrypted storage creates a persistent security risk where any individual with read access to the Jenkins master's file system can locate and extract these credentials without requiring additional authentication or authorization mechanisms. The vulnerability is particularly concerning because Jenkins masters typically run with elevated privileges and may be accessed by multiple administrators, increasing the attack surface for credential exposure. The flaw can be categorized under CWE-312 (Cleartext Storage of Sensitive Information) and aligns with ATT&CK technique T1552.001 (Unsecured Credentials) as it provides attackers with direct access to authentication tokens and credentials without requiring additional exploitation steps.
The operational impact of this vulnerability extends beyond simple credential theft, as it enables attackers to gain unauthorized access to integrated systems that rely on Spira for test management and quality assurance processes. Once compromised, attackers can manipulate test results, inject malicious code into the CI/CD pipeline, or gain access to sensitive project data stored within Spira systems. The vulnerability affects organizations that use Jenkins as their continuous integration platform and have integrated Spira for test management, potentially exposing critical development workflows and sensitive project information. The long-term implications include potential data breaches, supply chain compromises, and extended periods of unauthorized access that may go undetected due to the stealthy nature of credential theft. Organizations with multiple Jenkins instances or those using the plugin across distributed development teams face increased risk exposure, as the compromised credentials could provide access to multiple interconnected systems.
Mitigation strategies for this vulnerability require immediate remediation through plugin version updates to 3.2.3 or later, which address the credential storage issue by implementing proper encryption mechanisms. Organizations should also implement additional access controls and monitoring to detect unauthorized file system access attempts, while reviewing and restricting file system permissions for Jenkins master servers. The implementation of Jenkins' built-in credential management systems and the use of encrypted configuration files can provide additional layers of protection. Security teams should conduct comprehensive audits of all Jenkins plugins to identify similar vulnerabilities and ensure that all credential storage mechanisms follow industry best practices. Regular security assessments and penetration testing should include verification of credential storage practices to prevent similar issues from emerging in other components of the Jenkins infrastructure. The vulnerability highlights the importance of following security standards such as those outlined in NIST SP 800-53 and ISO/IEC 27001 for proper information security management.
