"The version of XOOPS running on the remote web server has a cross-
site scripting vulnerability.  'misc.php' does not sanitize the
requested URI before displaying it in the response.  Manipulating the
query string can result in a cross-site scripting attack.  A remote
attacker could exploit this by tricking a user into requesting a
malicious URL.

There are reportedly other unspecified vulnerabilities in this version
of XOOPS, though Nessus has not checked for those issues.");
