It provides bug tracking, issue tracking, and project management functions. Although normally styled JIRA, the product name is not an acronym, but a truncation of Gojira, the Japanese name for Godzilla, itself a reference to JIRA's main competitor, Bugzilla.

Login into JIRA v6.4 Step 2: Go to More -> Boards. Step 3: Click on Create New Board tab -> Create New Step 4: Insert XSS payload in "Board Name" parameter of Create New Board. I have used "><img src=x onerror=prompt(1);> XSS payload Step 5: Then click on Ok Step 6: Whenever anyone try to edit or refresh page, the alert XSS Script will get execute and also disclosing sensitive information on the page like Users Details, IDs, Status etc. *Impact of attack:* An attack can perform Cross Site Scripting attack and steal the cookie of other active sessions. An attacker would exploit a vulnerability within a website or web application that the victim would visit, essentially using the vulnerable website as a vehicle to deliver a malicious script to the victim’s browser. An attacker might be able to put stored XSS into the website. https://www.owasp.org/index.php/Cross-site_Scripting_(XSS) *Recommendation:* Use an appropriate combination of white listing and blacklisting to ensure only valid and expected input is processed by the system. Furthermore, classes within the output tag libraries should also be modified to encode potentially dangerous characters with their HTML escape Counter parts.
