An article from CNET shows how an attacker can use vulnerabilities in these services, such as buffer overflows, directory traversal, race conditions, command injections, and bad permissions to take over the router from the local network without knowing the administrative password. Some of the worst vulnerabilities were in undocumented, proprietary services that users cannot disable and allowed an attacker to achieve a root shell. The researchers who discovered the vulnerabilities will be demonstrating them at the Wall of Sheep and Wireless Village at DEF CON.
