Descriptions

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1330 1.13B01 BETA routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the SOAPAction HTTP header. 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 the device. Was ZDI-CAN-12029.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los routers D-Link DAP-1330 versiones 1.13B01 BETA. No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta en el manejo del encabezado HTTP SOAPAction. El problema resulta de la falta de comprobación apropiada de la longitud de los datos suministrados por el usuario antes de copiarlos en un búfer de fixed-length en la región stack de la memoria. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del dispositivo. Fue ZDI-CAN-12029
