Description

Vulnerability Description

FlatNuke contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'admin', 'admin_mail' and 'back' variables upon submission to the 'footer.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Solution Description

Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
