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.

Affected Products: C-Bus Network Automation Controller - LSS5500NAC (Versions prior to V1.10.0), Wiser for C-Bus Automation Controller - LSS5500SHAC (Versions prior to V1.10.0), Clipsal C-Bus Network Automation Controller - 5500NAC (Versions prior to V1.10.0), Clipsal Wiser for C-Bus Automation Controller - 5500SHAC (Versions prior to V1.10.0), SpaceLogic C-Bus Network Automation Controller - 5500NAC2 (Versions prior to V1.10.0), SpaceLogic C-Bus Application Controller - 5500AC2 (Versions prior to V1.10.0)

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 analysis
How this class of weakness works · CWE-287

The mechanism that verifies who a user is can be side-stepped or fooled, letting an attacker act as someone they're not. Everything built on top of that identity then becomes untrustworthy. Fixing it means hardening the full authentication flow, including edge cases, tokens, and secondary paths.

Recommended fix Moderate confidence

Firmware V1.10.0 or later (per official description) / V1.11.0 (per affected versions list)

  1. 1. Identify the current firmware version of the C-Bus Network Automation Controller (5500NAC/5500NAC2), Wiser for C-Bus Automation Controller (5500SHAC), or SpaceLogic C-Bus Application Controller (5500AC2) by accessing the device's web interface or administrative console.
  2. 2. Navigate to the Schneider Electric download portal or use the direct link: https://download.schneider-electric.com/files?p_enDocType=Security+and+Safety+Notice&p_File_Name=SEVD-2022-165-06_C-Bus_Home_Automation_Products_Security_Notification.pdf
  3. 3. Download the security notification document (SEVD-2022-165-06) to obtain the official patched firmware version and installation instructions.
  4. 4. Obtain the patched firmware version (V1.10.0 or later, or V1.11.0 per the affected versions list) from Schneider Electric's official support channels.
  5. 5. Backup the current device configuration before performing the firmware upgrade.
  6. 6. Upload and install the patched firmware following the vendor's documented upgrade procedure.
  7. 7. After upgrading, verify the firmware version has been updated and confirm the web login authentication vulnerability is resolved.
  8. 8. Change all default or previously used credentials as a precautionary security measure.
Caveat Review the security notification for any configuration changes required after upgrade; ensure backup of configuration before upgrading
