CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

OPERATING SYSTEM:
eSoft InstaGate
http://secunia.com/product/14790/

DESCRIPTION:
Daniel Weber has reported a vulnerability in eSoft InstaGate, which
can be exploited by malicious people to conduct cross-site request
forgery attacks.

The vulnerability is caused due to the web interface of the device
allowing users to perform certain actions via HTTP requests without
performing any validity checks to verify the request. This can be
exploited e.g. to change certain settings or to change the
administrator's password by enticing a logged-in administrator to
visit a malicious site.

The vulnerability is reported in eSoft InstaGate EX2. Other versions
may also be affected.

SOLUTION:
Update to firmware version 3.1.20070615 or later.
