DESCRIPTION:
Khashayar Fereidani has reported a vulnerability in Linksys WAG120N,
which can be exploited by malicious people to conduct cross-site
request forgery attacks.

The setup.cgi script allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. enable remote management or
change the administrator's password by tricking a logged in
administrator into visiting a malicious web site.

SOLUTION:
Do not browse untrusted web sites or follow untrusted links while
being logged-in to the application.

PROVIDED AND/OR DISCOVERED BY:
