CVE-2018-12735
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 · uneditedSAJ Solar Inverter allows remote attackers to obtain potentially sensitive information via a direct request for the inverter_info.htm or english_main.htm URI.
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 confidenceSAJ Solar Inverter web interface contains information disclosure vulnerability where sensitive data can be exposed via direct HTTP requests to inverter_info.htm or english_main.htm pages without proper authentication or authorization controls.

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.
-
Confirm Saj Solar Inverter is in useIdentify if the target environment contains a Saj Electric Saj Solar Inverter device. Check network inventory, device labels, or documentation for this specific product.Affected if The environment includes a Saj Electric Saj Solar Inverter device.
-
Locate the web management interfaceIdentify the IP address or hostname of the inverter's web interface. This is typically accessible on the local network via HTTP on port 80 or 8080.Affected if A web interface for the Saj Solar Inverter is reachable on the network.
-
Test inverter_info.htm for unauthenticated accessUsing a web browser or curl command, navigate directly to http://<inverter-ip>/inverter_info.htm without providing any login credentials. Observe if the page loads and displays any information.Affected if The inverter_info.htm page loads and displays data without requiring authentication.
-
Test english_main.htm for unauthenticated accessUsing a web browser or curl command, navigate directly to http://<inverter-ip>/english_main.htm without providing any login credentials. Observe if the page loads and displays any information.Affected if The english_main.htm page loads and displays data without requiring authentication.
-
Verify sensitive data exposureExamine the content returned from either page. Look for system configuration details, operational parameters, network settings, or other sensitive information that should require authentication to access.Affected if Either page reveals sensitive inverter data such as configuration, performance metrics, or network details without authentication.
If a Saj Solar Inverter web interface is accessible and either inverter_info.htm or english_main.htm pages return data without authentication, the environment is affected by CVE-2018-12735.

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.
From vendor dataImplement proper access control and authentication requirements on sensitive web pages, or remove sensitive information from these endpoints. Consider network segmentation to limit exposure of the inverter management interface.
