Device memory disclosure via unchecked file index
Published Dec 2, 2025 · Updated Dec 2, 2025
Out-of-bounds read in DownloadFile in Circutor SGE-PLC1000 and SGE-PLC50 9.0.2 allows remote authenticated users to read device memory. DownloadFile converts a file parameter with atoi() and uses the result directly as an index into FilesDownload without validating its bounds. An authenticated network request containing an oversized numeric index accesses memory outside the array; the published impact is limited to confidentiality.
