Descriptions

D-Link DCS-8300LHV2 ONVIF SetHostName Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DCS-8300LHV2 IP cameras. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

The specific flaw exists within the handling of the SetHostName ONVIF call. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21322.

Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria de D-Link DCS-8300LHV2 ONVIF SetHostName. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de cámaras IP D-Link DCS-8300LHV2. Aunque se requiere autenticación para aprovechar esta vulnerabilidad, se puede omitir el mecanismo de autenticación existente. La falla específica existe en el manejo de la llamada ONVIF SetHostName. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-21322.
