CVE-2022-34763
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-345: Insufficient Verification of Data Authenticity vulnerability exists that could cause loading of unauthorized firmware images due to improper verification of the firmware signature. Affected Products: X80 advanced RTU Communication Module (BMENOR2200H) (V2.01 and later), OPC UA Modicon Communication Module (BMENUA0100) (V1.10 and prior)
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.

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 · scopedFirmware version > V1.10 for OPC UA Module (BMENUA0100); Firmware version > V2.01 for X80 Advanced RTU (BMENOR2200H)
- 1. Identify the specific model number of the affected device (BMENUA0100 for OPC UA Module or BMENOR2200H for X80 Advanced RTU)
- 2. Determine the current firmware version installed on the device
- 3. For OPC UA Module (BMENUA0100): Upgrade firmware to a version higher than V1.10
- 4. For X80 Advanced RTU Module (BMENOR2200H): Upgrade firmware to a version higher than V2.01
- 5. Consult the Schneider Electric security notification SEVD-2022-193-01 for exact fixed version numbers
- 6. Follow Schneider Electric's standard firmware update procedure for the specific controller (M580 or X80 Advanced RTU)
- 7. Verify the firmware upgrade was successful and the new version is running
