Description

This strike emulates remote DNS hijack attacks for several D-LINK routers. The vulnerability resides in the 'dnscfg.cgi' script and is due to lack of authentication on server-side. A remote unauthenticated attacker may change the DNS configuration of the router which can result in man-in-the-middle attacks and information disclosure.
