Cisco DDR2200 ADSL2 Residential Gateway Router Vulnerabilities

I have discovered two Vulnerabilities in the Cisco DDR2200 ADSL2 Residential Gateway Router. The first vulnerability is that this device responds to UPNP multicast packets and UPNP SOAP requests out side of its local area network. Allowing attackers to forward ports and redirect traffic with out being authenticated, all of which can be exploited using dc414’s Upnp Exploiter.

The second vulnerability is remote command execution in the web based ping function. You can inject a pipe “|” followed by your command and it will get run on the shell and return the results as shown below.
