TITLE:
ZyXEL P-330W Cross-Site Scripting and Request Forgery Vulnerabilities

SECUNIA ADVISORY ID:
SA28172

VERIFY ADVISORY:
http://secunia.com/advisories/28172/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

OPERATING SYSTEM:
ZyXEL P-330W
http://secunia.com/product/17060/

DESCRIPTION:
Some vulnerabilities have been reported in ZyXEL P-330W, which can be
exploited by malicious people to conduct cross-site scripting and
request forgery attacks.

1) Input passed to the parameter "pingstr" in ping.asp is not
properly sanitised before being returned to a 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) Various vulnerabilities are 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. change the administrator's password.

Note: Reportedly, the router runs a vulnerable version of GoAhead
WebServer, which potentially can be exploited by malicious people to
compromise the device.

SOLUTION:
Do not browse other websites while being logged into the device.
