Linksys WRT160N DHCP Client Table HTML Injection Vulnerability

Linksys WRT160N is prone to an HTML-injection vulnerability because it fails to sufficiently sanitize user-supplied input data.

Exploiting this issue may allow an attacker to execute HTML and script code in the context of the device, to steal cookie-based authentication credentials, or to control how the site is rendered to the user; other attacks are also possible.
