Java vulnerability analysis and mitigation

Zephyr for JIRA Test Management Plugin 1.5 and earlier contains a security vulnerability identified as CVE-2020-2154. The vulnerability was discovered and disclosed on March 9, 2020. This vulnerability affects the Jenkins plugin's credential storage mechanism, specifically impacting installations of Zephyr for JIRA Test Management Plugin versions up to and including 1.5 (Jenkins Advisory, OSS Security).

The vulnerability is related to insecure credential storage, where Jira credentials are stored unencrypted in the global configuration file 'com.thed.zephyr.jenkins.reporter.ZfjReporter.xml' on the Jenkins controller. The severity of this vulnerability is rated as Low according to the CVSS scoring system (Jenkins Advisory).

The vulnerability exposes Jira credentials to unauthorized access. Users who have access to the Jenkins controller file system can view these credentials in plain text, potentially compromising the security of the connected Jira instance (Jenkins Advisory).

The vulnerability can be exploited by users who have access to the Jenkins controller file system. No special exploitation tools or techniques are required as the credentials are stored in plain text and can be directly read from the configuration file (Jenkins Advisory).

As of the advisory publication date, no official fix was available for this vulnerability. Organizations using affected versions should implement strict access controls to the Jenkins controller file system to minimize the risk of credential exposure (Jenkins Advisory).
