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
Autel Maxi Charger Single firmware through V1.03.51 is vulnerable to OS command injection when processing OCPP GetDiagnostics requests. A malicious or compromised OCPP server can supply a crafted diagnostics URL that results in arbitrary command execution on the charging station.

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

Autel Maxi Charger Single firmware through V1.03.51 contains an OS command injection vulnerability in the OCPP GetDiagnostics handler. The diagnostics URL parameter is not properly sanitized before being passed to a system call, allowing an authenticated or man-in-the-middle attacker controlling the OCPP server to execute arbitrary commands on the charging station with root or elevated privileges.

MitigationUpdate firmware to a version beyond V1.03.51 when available, and restrict OCPP server connections to only trusted, authorized servers to prevent malicious server injection.

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. Check the device firmware version
    Access the Autel Maxi Charger admin interface or use the device's diagnostic menu to retrieve the current firmware version. This is typically found under System Info, About, or Maintenance settings.
    Affected if The installed firmware version is lower than V1.03.51 (for example, V1.03.50, V1.02.x, or earlier)
  2. Verify OCPP is enabled
    Locate the OCPP configuration settings in the charging station admin panel. OCPP is typically configured under Network Settings, Communication Protocols, or OCPP Settings.
    Affected if OCPP support is enabled and the station is configured to connect to an OCPP server
  3. Inspect OCPP server connection settings
    Review the OCPP server URL or endpoint configuration in the charging station. This defines which OCPP server the station communicates with for operations like diagnostics retrieval.
    Affected if The station is configured to connect to an untrusted or externally accessible OCPP server, or no server whitelist is enforced
  4. Check GetDiagnostics handler configuration
    Look for GetDiagnostics or diagnostic retrieval settings within the OCPP module configuration. This feature allows the station to send diagnostic logs to a configured OCPP server.
    Affected if GetDiagnostics functionality is available and the station can initiate diagnostics retrieval to a remote server

The environment is affected if the Autel Maxi Charger firmware is below V1.03.51 AND OCPP with GetDiagnostics is enabled, allowing the station to contact a potentially malicious OCPP server.

From vendor data
Upgrade available Upgrade to a release after 1.03.51
Interim mitigation

Update firmware to a version beyond V1.03.51 when available, and restrict OCPP server connections to only trusted, authorized servers to prevent malicious server injection.
