JIRA (/ˈdʒɪərə/ JEER-ə) is a proprietary issue tracking product, developed by Atlassian, commonly used for bug tracking, issue tracking, and project management. It has been developed since 2002. JIRA is a commercial software product that can be licensed for running on-premises or available as a hosted solution.
GreenHopper – GreenHopper unlocks the power of Agile, whether you’re a seasoned Agile expert or just getting started. Creating user stories, estimating those stories for a sprint backlog, identifying team velocity, visualizing team activity and reporting progress has never been so easy.


Our researchers discovered a Stored XSS vulnerability allowing an attacker to inject arbitrary script code into an existing and fully patched JIRA + GreenHopper installations (JIRA=V4.4.3, GreenHopper prior to V5.9.8).
The requirements for a successful attack are minimal:
A user logged into the targeted JIRA issue tracking system needs to be convinced to visit an attacker controlled link.
Once that link has been visited by the unsuspecting victim, an invisible form will perform a POST request and the victim will be redirected to a URL where username, password and login credentials such as cookies can be read and processed by the attacker.
An attacker can obtain access to privileged accounts and get control over the JIRA issue tracker and connected systems.
