## Overview

Out-of-bounds read vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The 'DownloadFile' function converts a parameter to an integer using 'atoi()' and then uses it as an index in the 'FilesDownload' array with '(&FilesDownload)[iVar2]'. If the parameter is too large, it will access memory beyond the limits.

## Affected

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

## Remediation
