CVE-2025-36743
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 · uneditedSolarEdge SE3680H has an exposed debug/test interface accessible to unauthenticated actors, allowing disclosure of system internals and execution of debug commands.
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 · moderate confidenceThe SolarEdge SE3680H inverter contains an exposed debug/test interface accessible without authentication. This allows unauthenticated attackers to retrieve system internals (configuration, credentials, logs) and execute debug commands, potentially leading to further compromise of the device and connected systems.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device web interface or check the physical device label to confirm the model is SolarEdge SE3680HAffected if The device model is SolarEdge SE3680H
-
Check the installed firmware versionLog into the device web interface and navigate to the System Information or About section to view the firmware versionAffected if The firmware version is 4.0 or higher but below 4.22
-
Determine if the debug interface is network-accessibleScan the device IP for open ports typically associated with debug interfaces (such as telnet port 23, custom debug ports, or web endpoints like /debug, /diag, or /shell). Attempt to access these from an untrusted network perspective.Affected if Port scanning reveals open debug service ports or web paths that respond without authentication
You are affected if you have a SolarEdge SE3680H inverter running firmware version 4.0 through 4.21 with the debug/test interface exposed to untrusted networks.
Generated from the published advisory. Verify against your own configuration.
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 · scoped4.22
Disable or restrict the debug/test interface via network segmentation, firewall rules, or firmware update from SolarEdge. If a firmware patch is available, apply it. If the interface cannot be disabled, ensure it is unreachable from untrusted networks.
4.22
- Verify current firmware version on the SolarEdge SE3680H device through the device interface or monitoring platform
- Obtain firmware version 4.22 or later from SolarEdge's official firmware distribution (contact SolarEdge support or use their official update channel)
- Apply the firmware update following SolarEdge's standard firmware upgrade procedure for the SE3680H model
- Confirm the device is running firmware version 4.22 or higher after the update
