CVE-2025-11783

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.

Summary		(es) Vulnerabilidad de desbordamiento de búfer basado en pila en Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. La vulnerabilidad se encuentra en la función 'AddEvent()' al copiar la entrada de nombre de usuario controlada por el usuario a un búfer de tamaño fijo (48 bytes) sin verificación de límites. Esto puede llevar a corrupción de memoria, resultando en una posible ejecución remota de código.
