"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, an attacker could 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 a phpBB 
    administrator to visit a specially crafted link, an attacker
    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.");
