CVE-2022-32523
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA CWE-120: Buffer Copy without Checking Size of Input vulnerability exists that could cause a stack-based buffer overflow, potentially leading to remote code execution when an attacker sends specially crafted online data request messages. Affected Products: IGSS Data Server - IGSSdataServer.exe (Versions prior to V15.0.0.22170)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedIGSS V15.0.0.22170 or later
- 1. Identify all IGSS Data Server installations (IGSSdataServer.exe) in the environment and note their current versions.
- 2. Download the security patch from the vendor reference: https://download.schneider-electric.com/files?p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2022-165-01_IGSS_Security_Notification_V2.pdf
- 3. Review the patch release notes to confirm it contains the fix for CVE-2022-32523 (CWE-120 buffer overflow).
- 4. Create a backup of the current IGSS configuration and database files before applying the update.
- 5. Apply version 15.0.0.22170 or later of IGSS Data Server to all affected installations.
- 6. Verify the installed version matches the target (15.0.0.22170 or higher).
- 7. Restart the IGSS Data Server service to ensure the patched code is loaded.
- 8. Test critical IGSS functionality to confirm normal operations after patching.
