TITLE:
D-Link DVG-2001S Cross-Site Scripting and Cross-Site Request Forgery

SECUNIA ADVISORY ID:
SA33738

VERIFY ADVISORY:
http://secunia.com/advisories/33738/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

OPERATING SYSTEM:
D-Link DVG-2001S VoIP Phone Adapter
http://secunia.com/advisories/product/21310/

DESCRIPTION:
Some vulnerabilities have been reported in D-Link DVG-2001S, which
can be exploited by malicious people to conduct cross-site scripting
and cross-site request forgery attacks.

1) Input passed via the URL to Forms/page_CfgDevInfo_Set is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

2) The device 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. upload a different firmware
by tricking the user into visiting a malicious web site.

The vulnerabilities are reported in firmware version 1.00.007. Other
versions may also be affected.

SOLUTION:
Filter malicious characters and character sequences in a proxy.

Do not visit other sites while being logged in to the device.
