Description

phpBB contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the '[flash=]' BBCode tag upon submission to the includes/message_parser.php script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
