Description: r0t has discovered a vulnerability in Atlassian JIRA Enterprise Edition, which can be exploited by malicious people to disclose system information and conduct cross-site scripting attacks.
Input passed via the URL when accessing "secure/ConfigureReleaseNote.jspa" directly isn't properly sanitised before being returned to the user in an error response. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The returned error response also contains various system information.
