Background
The Jenkins Jira Plugin is a plugin for the Jenkins automation server that allows integration with Jira, a popular issue tracking and project management tool. It provides functionality to connect Jenkins to Jira instances and perform various actions, such as creating issues, updating issues, and retrieving issue information. The plugin is commonly used in software development and continuous integration workflows to streamline the management of issues and track their progress. However, versions 3.0.1 and earlier of the plugin are vulnerable to an improper authorization issue.
Vulnerability Detail
The vulnerability in the Jenkins Jira Plugin allows attackers with Overall/Read access to have Jenkins connect to a URL specified by the attacker using credentials IDs obtained through another method. This can lead to the capture of credentials stored in Jenkins. The issue is present in the JiraSite.java file of the plugin. In version 3.0.2, the form validation method has been updated to require POST requests and specific permissions (Overall/Administer or Item/Configure) to mitigate the vulnerability. The vulnerability has a CVSS score of 4.2, indicating a moderate severity level.

Workaround
If upgrading to version 3.0.2 is not immediately possible, a temporary workaround is to restrict access to the Jenkins instance and ensure that only trusted users with appropriate permissions have Overall/Read access. Additionally, it is recommended to monitor the Jenkins logs for any suspicious activity and regularly review and rotate the stored credentials to minimize the potential impact of the vulnerability.
Conclusion
The Jenkins Jira Plugin versions 3.0.1 and earlier are vulnerable to an improper authorization issue that can allow attackers to capture credentials stored in Jenkins. It is crucial to upgrade to version 3.0.2 or later to mitigate the vulnerability. Restricting access to the Jenkins instance and monitoring for suspicious activity are recommended as temporary measures.
