Executive Summary

This vulnerability is a stack-based buffer overflow in Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2. It occurs in the 'AddEvent()' function when a user-controlled username input is copied into a fixed-size buffer of 48 bytes without proper boundary checking. This improper handling can cause memory corruption, which may allow an attacker to execute code remotely on the affected device.

Impact Analysis

The vulnerability can lead to memory corruption and potentially allow remote code execution on the affected Circutor devices. This means an attacker could gain unauthorized control over the device, potentially disrupting its operation or using it as a foothold to attack other parts of the network.

Mitigation Strategies

The affected Circutor SGE-PLC1000/SGE-PLC50 devices are discontinued since 2015 and have been replaced by newer models. It is recommended to update the firmware to version 2.0.0 or later to mitigate this and related vulnerabilities. [1]
