CVE-2017-10720 WRITEUP HIGH WRITEUP
Shekar Endoscope Firmware - Stack Overflow via Wi-Fi Name Parameter
Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that the desktop application used to connect to the device suffers from a stack overflow if more than 26 characters are passed to it as the Wi-Fi name. This application is installed on the device and an attacker who can provide the right payload can execute code on the user's system directly. Any breach of this system can allow an attacker to get access to all the data that the user has access too. The application uses a dynamic link library(DLL) called "avilib.dll" which is used by the application to send binary packets to the device that allow to control the device. One such action that the DLL provides is change password in the function "sendchangename" which allows a user to change the Wi-Fi name on the device. This function calls a sub function "sub_75876EA0" at address 0x758784F8. The function determines which action to execute based on the parameters sent to it. The "sendchangename" passes the datastring as the second argument which is the name we enter in the textbox and integer 1 as first argument. The rest of the 3 arguments are set to 0. The function "sub_75876EA0" at address 0x75876F19 uses the first argument received and to determine which block to jump to. Since the argument passed is 1, it jumps to 0x75876F20 and proceeds from there to address 0x75876F56 which calculates the length of the data string passed as the first parameter. This length and the first argument are then passed to the address 0x75877001 which calls the memmove function which uses a stack address as the destination where the password typed by us is passed as the source and length calculated above is passed as the number of bytes to copy which leads to a stack overflow.

CVE-2017-10721 WRITEUP MEDIUM WRITEUP
Shekar Endoscope Camera Firmware - Unauthenticated Telnet Access
Recently it was discovered as a part of the research on IoT devices in the most recent firmware for Shekar Endoscope that the device has Telnet functionality enabled by default. 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.

CVE-2007-0228 EXPLOITDB python WORKING POC
EIQ Networks Enterprise Security Analyzer - Denial of Service via Malformed TCP Packet to Port 10618
The DataCollector service in EIQ Networks Network Security Analyzer allows remote attackers to cause a denial of service (service crash) via a (1) &CONNECTSERVER& (2) &ADDENTRY& (3) &FIN& (4) &START& (5) &LOGPATH& (6) &FWADELTA& (7) &FWALOG& (8) &SETSYNCHRONOUS& (9) &SETPRGFILE&, or (10) &SETREPLYPORT& string to TCP port 10618, which triggers a NULL pointer dereference.
