Description
Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'ShowMeterDatabase()' function, there is an unlimited user input that is copied to a fixed-size buffer via 'sprintf()'. The 'GetParameter(meter)' function retrieves the user input, which is directly incorporated into a buffer without size validation. An attacker can provide an excessively large input for the 'meter' parameter.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack-based buffer overflow in Circutor SGE-PLC1000/SGE-PLC50 version 9.0.2. It occurs in the 'ShowMeterDatabase()' function where user input from the 'meter' parameter is retrieved by 'GetParameter(meter)' and copied into a fixed-size buffer using 'sprintf()' without validating the input size. An attacker can exploit this by providing an excessively large input, causing memory corruption.


How can this vulnerability impact me? :

Exploiting this vulnerability can lead to memory corruption, which may allow an attacker to execute arbitrary code, crash the device, or cause denial of service. Since the vulnerability involves unsafe handling of user input, it could be leveraged to compromise the affected Circutor devices, potentially disrupting electricity network management functions.


What immediate steps should I take to mitigate this vulnerability?

The affected Circutor SGE-PLC1000/SGE-PLC50 devices are discontinued since 2015 and have been replaced by newer models (Compact DC and GEDE EDC). It is recommended to update the firmware to version 2.0.0 or later to mitigate these issues. [1]
