Descriptions
An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The binary rtspd in /sbin folder of the device handles all the rtsp connections received by the device. It seems that the binary performs a memcpy operation at address 0x00011E34 with the value sent in the "Authorization: Basic" RTSP header and stores it on the stack. The number of bytes to be copied are calculated based on the length of the string sent in the RTSP header by the client. As a result, memcpy copies more data then it can hold on stack and this results in corrupting the registers for the caller function sub_F6CC which results in memory corruption. The severity of this attack is enlarged by the fact that the same value is then copied on the stack in the function 0x00011378 and this allows to overflow the buffer allocated and thus control the PC register which will result in arbitrary code execution on the device.
Se detectó un problema en los dispositivos DCS-1100 y DCS-1130 de D-Link. El rtspd binario en la carpeta /sbin del dispositivo maneja todas las conexiones rtsp recibidas por el dispositivo. Al parecer el binario realiza una operación memcpy en la dirección 0x00011E34 con el valor enviado en el encabezado RTSP "Authorization: Basic" y lo almacena en la pila. El número de bytes que se copiarán se calcula según la longitud de la cadena enviada por el cliente en el encabezado RTSP. Como resultado, memcpy copia más datos que luego puede mantener en la pila y esto resulta en una corrupción de los registros sub_F6CC de la función caller, lo que resulta en la corrupción de la memoria. La severidad de este ataque se incrementa por el hecho de que el mismo valor se copia en la pila en la función 0x00011378 y esto permite desbordar el búfer asignado y, por lo tanto, controlar el registro de la PC, que resultará en una ejecución de código arbitraria en el dispositivo.
Dlink DCS-1130 suffers from command injection, cross site request forgery, stack overflow, and various other vulnerabilities.
