IMPACT:
Cross Site Scripting

OPERATING SYSTEM:
Linksys WRT54GL 4.x

DESCRIPTION:
Tomaz Bratusa has reported a vulnerability in Linksys WRT54GL, which
can be exploited by malicious people to conduct cross-site request
forgery attacks.

The vulnerability is caused due to the device allowing users to
perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to e.g.
disable the firewall by enticing a logged-in administrator to visit a
malicious site.

The vulnerability is reported in firmware version 4.30.9. Other
versions may also be affected.

SOLUTION:
The vendor is currently working on a fix.

Do not browse untrusted websites or follow untrusted links while
logged on to the application.
