linkscript - leave-link.cgi
download from: http://www.newbreedsoftware.com/
problem description:
the unchecked parameter "file" and "url" allows an attacker
to create and write "any" file on system with webservers permissions.
(which makes it pretty dangerous)
example:
http://www.dumbasssite.com/cgi-bin/leave-link.cgi?file=yes.php3&url=xxxx
creates file: "./yes.php3" with content:"<timestamp>:" xxxxx
