D-Link DSL-2730U

Cross Site Request Forgery (CSRF) on D-Link DSL-2730U C1 IN_1.00 devices allows remote attackers to change the DNS or firewall configuration or any password.

D-Link DSL 2730-U IN_1.10 and IN_1.11 and DIR-600M 3.04 devices have the domain.name string in the DNS resolver search path by default, which allows remote attackers to provide valid DNS responses (and also offer Internet services such as HTTP) for names that otherwise would have had an NXDOMAIN error, by registering a subdomain of the domain.name domain name.

D-Link (Non-US) DSL-2750U N300 ADSL2+ and (Non-US) DSL-2730U N150 ADSL2+ are vulnerable to Incorrect Access Control. The UART/Serial interface on the PCB, provides log output and a root terminal without proper access control.

The restricted telnet shell on the D-Link DSL2730U router allows remote authenticated users to bypass intended command restrictions via shell metacharacters that follow a whitelisted command.
