The remote web server hosts an application that is vulnerable to a Cross-Site Scripting (XSS) attack vector.
The version of JIRA installed on the remote host is earlier than 6.0.2 and is affected by a flaw that allows an XSS attack. This flaw exists because the '/secure/GHCreateNewIssue.jspa' script does not validate input to the 'fieldsKeys' parameter before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
Update to JIRA 6.0.x version 6.0.2 or later.
