Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is affected by
multiple vulnerabilities.

Description :

According to its banner, the remote host is running a version of phpBB
that suffers from multiple flaws:

- A BBCode Input Validation Vulnerability
The application fails to properly filter for the BBCode
URL in the 'includes/bbcode.php' script. With a specially-
crafted URL, a possible hacker cause arbitrary script code to be
executed in a user's browser, possibly even to modify
registry entries without the user's knowledge.

- Cross-Site Scripting Vulnerabilities
The application does not properly sanitize user-supplied input
to the 'forumname' and 'forumdesc' parameters of the
'admin/admin_forums.php' script. By enticing an phpBB
administrator to visit a a specially-crafted link, a possible hacker
can potentially steal the admin's session cookie or perform
other attacks.

- Improper Filtering of HTML Code
The application does not completely filter user-supplied input
to the 'u' parameter of the 'profile.php' script or the
'highlight' parameter of the 'viewtopic.php' script.
