CVE-2025-11782

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The 'ShowDownload()' function uses “sprintf()” to format a string that includes the user-controlled input of 'GetParameter(meter)' in the fixed-size buffer 'acStack_4c' (64 bytes) without checking the length. An attacker can provide an excessively long value for the 'meter' parameter that exceeds the 64-byte buffer size.

Summary		(es) Vulnerabilidad de desbordamiento de búfer basado en pila en Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. La función 'ShowDownload()' utiliza “sprintf()” para formatear una cadena que incluye la entrada controlada por el usuario de 'GetParameter(meter)' en el búfer de tamaño fijo 'acStack_4c' (64 bytes) sin verificar la longitud. Un atacante puede proporcionar un valor excesivamente largo para el parámetro 'meter' que excede el tamaño del búfer de 64 bytes.
