A vulnerability classified as critical was found in D-Link DIR-880L up to 104WWb01. Affected by this vulnerability is the function sub16570 of the file /htdocs/ssdpcgi of the component Request Header Handler. The manipulation of the argument HTTPST/REMOTEADDR/REMOTEPORT/SERVERID leads to command injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

D-Link DIR-822 Rev.B 202KRb06, DIR-822 Rev.C 3.10B06, DIR-860L Rev.B 2.03.B03, DIR-868L Rev.B 2.05B02, DIR-880L Rev.A 1.20B0101i3seBETA, and DIR-890L Rev.A 1.21B02BETA devices mishandle IsAccessPoint in /HNAP1/SetAccessPointMode. In the SetAccessPointMode.php source code, the IsAccessPoint parameter is saved in the ShellPath script file without any regex checking. After the script file is executed, the command injection occurs. A vulnerable /HNAP1/SetAccessPointMode XML message could have shell metacharacters in the IsAccessPoint element such as the telnetd string.

D-Link DIR-822 C1 before v3.11B01Beta, DIR-822-US C1 before v3.11B01Beta, DIR-850L A before v1.21B08Beta, DIR-850L B before v2.22B03Beta, and DIR-880L A before v1.20B02Beta devices allow authentication bypass.

Processing malformed SOAP messages when performing the HNAP Login action causes a buffer overflow in the stack in some D-Link DIR routers. The vulnerable XML fields within the SOAP body are: Action, Username, LoginPassword, and Captcha. The following products are affected: DIR-823, DIR-822, DIR-818L(W), DIR-895L, DIR-890L, DIR-885L, DIR-880L, DIR-868L, and DIR-850L.

Multiple D-Link routers contain an unspecified vulnerability that allows for execution of OS commands.
