Arbitrary script execution is possible when posting a link in the
messages like this: [a]http://host.com/[/a]
Script: action.php
Variable: $txt
Script dont check $url for valid url. javascript code insertion is
possible: [a]javascript:alert("hello")[/a]

if somebody will click this link javascript will be executed.

Sorry. There is a small mistake.
this link show users profile. so this vulnerability allays to view files
with some extentions.
Directory traversal is possible registration form too. It allows to
create files(with some extentions) on server (write access is needed)
