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 problem with missing authorization on SolaX Cloud platform allows taking over any SolaX solarpanel inverter of which the serial number is known.

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 confidence

Missing authorization in SolaX Cloud allows attackers to take control of any inverter by knowing its serial number, enabling unauthorized account takeover without proper authentication verification.

MitigationContact SolaX for platform-level patch; monitor inverter accounts for suspicious activity; implement additional account security measures such as MFA if available.

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. Confirm SolaX Cloud connection
    Log into your SolaX Cloud account and navigate to the device/inverter list to verify your inverters are managed through this platform
    Affected if Your inverters are connected to SolaX Cloud and can be managed through the cloud portal
  2. Review authorized inverters in your account
    Check the inverter list in your SolaX Cloud account for any unknown or unauthorized devices that may have been added using only a serial number
    Affected if You see inverters in your account that you did not register or authorize
  3. Examine account access logs
    Look for access logs or activity history in your SolaX Cloud account settings for entries showing access from unknown IP addresses or at unusual times
    Affected if There are login or access events you cannot explain
  4. Verify account security settings
    Check your SolaX Cloud account profile for available security options such as multi-factor authentication (MFA)
    Affected if MFA is not enabled or not available, meaning your account relies solely on password authentication
  5. Confirm your inverter serial number is protected
    Review whether your inverter serial number is displayed publicly or shared in forums, social media, or third-party monitoring services
    Affected if Your inverter serial number is publicly exposed and could be used by an attacker

You are affected if your inverters are connected to SolaX Cloud and unauthorized devices or access appear in your account, or if your account lacks additional authentication safeguards beyond password alone.
