Identify the affected asset
Confirm whether Schneider Electric EasyLogic T150 (formerly Saitel DR) Remote Terminal Unit & Controller, Saitel DP Remote Terminal Unit & Controller, easylogic t150 firmware is installed, record the deployed version and installation path, and identify exposed interfaces.
- Record the product name, package or appliance identifier, and installed version.
- Identify internet-facing, administrative, API, and internal access paths.
- Preserve the pre-change configuration and relevant service logs.
Validate the affected-version match
Compare the deployed version with the affected range: >= Version 11.06.30 and prior, >= Version 11.06.35 and prior, < 11.06.32, < 11.06.38. Treat incomplete inventory results as unresolved.
Prioritize with independent signals

Apply supported remediation
Follow the vendor advisory or supported update path. Current fixed-version status: 11.06.32, 11.06.38. Preserve configuration and rollback material before change.
Verify the result
Confirm the resulting version, service health, authentication and access paths, monitoring coverage, and relevant security logs.
- Confirm the expected version and package state.
- Run a functional health check for critical service paths.
- Review authentication, error, application, and security monitoring logs.
- Reassess exposure if the supported fix cannot be applied.
