D-Link routers with the mydlink feature have some web interfaces without authentication requirements. An attacker can remotely obtain users' DNS query logs and login logs. Vulnerable targets include but are not limited to the latest firmware versions of DIR-817LW (A1-1.04), DIR-816L (B1-2.06), DIR-816 (B1-2.06?), DIR-850L (A1-1.09), and DIR-868L (A1-1.10).

There are some web interfaces without authentication requirements on D-Link DIR-868L B1-2.03 and DIR-817LW A1-1.04 routers. An attacker can get the router's username and password (and other information) via a DEVICE.ACCOUNT value for SERVICES in conjunction with AUTHORIZED_GROUP=1%0a to getcfg.php. This could be used to control the router remotely.
