## Overview

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.

## Affected

- `sge-plc1000_firmware = 9.0.2`
- `sge-plc50_firmware = 9.0.2`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
