D-Link DSL 2730-U IN1.10 and IN1.11 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 DIR-600M C1 3.04 devices allow authentication bypass via a direct request to the wan.htm page. NOTE: this may overlap CVE-2019-13101.

D-Link DIR-600M devices allow XSS via the Hostname and Username fields in the Dynamic DNS Configuration page.
