A NULL pointer dereference in D-Link DIR-860L REVBFIRMWARE2.04.B04ic5b allows attackers to cause a Denial of Service (DoS) via a crafted HTTP request.

In D-Link DIR-860L v2.03, there is a buffer overflow vulnerability due to the lack of length verification for the SID field in gena.cgi. Attackers who successfully exploit this vulnerability can cause the remote target device to crash or execute arbitrary commands.

In D-Link DIR-860L REVA FIRMWARE PATCH 1.10..B04, the Telnet service contains hardcoded credentials, enabling attackers to log in remotely to the Telnet service and perform arbitrary commands.

UNSUPPORTED WHEN ASSIGNED webinc/js/info.php on D-Link DIR-816L 2.06.B09BETA and DIR-803 1.04.B02 devices allows XSS via the HTTP Referer header. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: this is typically not exploitable because of URL encoding (except in Internet Explorer) and because a web page cannot specify that a client should make an additional HTTP request with an arbitrary Referer header.

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.

On D-Link DIR-818LW Rev.A 2.05.B03 and DIR-860L Rev.B 2.03.B03 devices, unauthenticated remote OS command execution can occur in the soap.cgi service of the cgibin binary via an "&&" substring in the service parameter. NOTE: this issue exists because of an incomplete fix for CVE-2018-6530.

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