Name of the Vulnerable Software and Affected Versions Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2

Description A stack-based buffer overflow exists in Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2. The ShowMeterDatabase() function copies user-controlled input into a fixed-size buffer using sprintf() without proper size validation. The GetParameter(meter) function retrieves user input for the meter parameter and incorporates it into a buffer without size checks, allowing an attacker to provide an excessively large input.
