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 · unedited
A vulnerability was found in Acrel Electrical EEMS Enterprise Power Operation and Maintenance Cloud Platform 1.3.0. This impacts an unknown function of the file /SubstationWEBV2/main/uploadH5Files. The manipulation of the argument File results in unrestricted upload. The attack may be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

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 · high confidence

Unrestricted file upload vulnerability in the /SubstationWEBV2/main/uploadH5Files endpoint of Acrel EEMS platform v1.3.0. The File argument lacks proper validation of file type, content, or extension, allowing attackers to upload malicious files (e.g., web shells) that could lead to remote code execution.

MitigationImplement strict file validation including allowlist-based extension checking, MIME type verification, content inspection, file size limits, and rename uploaded files; place uploaded files outside web root with random names.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Acrel EEMS platform is deployed
    Search for files, services, or web paths related to SubstationWEBV2, EEMS, or Acrel in your environment. Check running web applications for routes containing '/SubstationWEBV2/'.
    Affected if The system runs the Acrel EEMS platform software
  2. Verify the installed version of Acrel EEMS
    Locate version information in application metadata, config files, or the web interface (e.g., about page, footer version string). Compare against the affected version v1.3.0.
    Affected if The installed version is v1.3.0
  3. Confirm the uploadH5Files endpoint is accessible
    Attempt to access or enumerate the /SubstationWEBV2/main/uploadH5Files endpoint via HTTP/HTTPS, or inspect the application's routing configuration for this path.
    Affected if The endpoint /SubstationWEBV2/main/uploadH5Files exists and is reachable
  4. Test for missing file validation
    Send a test upload request to the endpoint with a file containing unexpected content (e.g., a .txt file with script code or an unconventional extension) and observe whether the system accepts it without validation errors.
    Affected if The endpoint accepts files without validating type, content, or extension

Your environment is affected if you run Acrel EEMS v1.3.0 with the /SubstationWEBV2/main/uploadH5Files endpoint exposed and no file validation enforced on uploads.
