The UPnP endpoint URL /gena.cgi in the D-Link DIR-859 Wi-Fi router 1.05 and 1.06B01 Beta01 allows an Unauthenticated remote attacker to execute system commands as root, by sending a specially crafted HTTP SUBSCRIBE request to the UPnP service when connecting to the local network.

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

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.

Certain D-Link products are affected by: Buffer Overflow. This affects DIR-880L 1.08B04 and DIR-895 L/R 1.13b03. The impact is: execute arbitrary code (remote). The component is: htdocs/fileaccess.cgi. The attack vector is: A crafted HTTP request handled by fileacces.cgi could allow an attacker to mount a ROP attack: if the HTTP header field CONTENTTYPE starts with ''boundary=' followed by more than 256 characters, a buffer overflow would be triggered, potentially causing code execution.

The D-Link router DIR-880L 1.07 is vulnerable to credentials disclosure in telnet service through decompilation of firmware, that allows an unauthenticated attacker to gain access to the firmware and to extract sensitive data.
