Description

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The vulnerability is found in the 'AddEvent()' function when copying the user-controlled username input to a fixed-size buffer (48 bytes) without boundary checking. This can lead to memory corruption, resulting in possible remote code execution.
