      "value": "Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that an attacker connected to the device Wi-Fi SSID can exploit a memory corruption issue and execute remote code on the device. This device acts as an Endoscope camera that allows its users to use it in various industrial systems and settings, car garages, and also in some cases in the medical clinics to get access to areas that are difficult for a human being to reach. Any breach of this system can allow an attacker to get access to video feed and pictures viewed by that user and might allow them to get a foot hold in air gapped networks especially in case of nation critical infrastructure/industries. The firmware contains binary uvc_stream that is the UDP daemon which is responsible for handling all the UDP requests that the device receives. The client application sends a UDP request to change the Wi-Fi name which contains the following format: \"SETCMD0001+0001+[2 byte length of wifiname]+[Wifiname]. This request is handled by \"control_Dev_thread\" function which at address \"0x00409AE0\" compares the incoming request and determines if the 10th byte is 01 and if it is then it redirects to 0x0040A74C which calls the function \"setwifiname\". The function \"setwifiname\" uses a memcpy function but uses the length of the payload obtained by using strlen function as the third parameter which is the number of bytes to copy and this allows an attacker to overflow the function and control the $PC value."

Este dispositivo actúa como una cámara endoscópica que permite a sus usuarios usarla en diversos sistemas y configuraciones industriales, talleres de coches y también, en ciertos casos, en clínicas médicas para acceder a áreas que son difíciles de alcanzar para un ser humano. Cualquier violación de este sistema puede permitirle a un atacante obtener acceso a fuentes de video e imágenes que visualiza ese usuario, y podría permitirle tener un pie firme en redes con protección Air Grap, especialmente en el caso de infraestructuras/industrias críticas para la nación. El firmware contiene uvc_stream binario que es el demonio UDP que es responsable de manejar todas las solicitudes UDP que recibe el dispositivo. La aplicación cliente envía una solicitud UDP para cambiar el nombre de Wi-Fi que contiene el siguiente formato: \"SETCMD0001+0001+[2 byte length of wifiname]+[Wifiname]. Esta solicitud es manejada por la función \"control_Dev_thread\" que se encuentra en la dirección \"0x00409AE0\" compara la solicitud entrante y determina si el décimo byte es 01 y si es así, redirige a 0x0040A74C que llama a la función \"setwifiname\". La función \"setwifiname\" usa una función memcpy pero utiliza la longitud de la carga obtenida usando la función strlen como el tercer parámetro, que es el número de bytes a copiar y esto le permite a un atacante desbordar la función y controlar el valor $PC."
