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 MaxiCharger AC Wallbox Commercial PIN Missing Authentication Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Autel MaxiCharger AC Wallbox Commercial charging stations. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Pile API. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to disclose credentials, leading to further compromise. Was ZDI-CAN-26352.

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

This vulnerability in Autel MaxiCharger AC Wallbox Commercial charging stations allows remote unauthenticated attackers to access the Pile API and disclose sensitive credentials. The flaw stems from missing authentication checks on specific API endpoints, enabling attackers to obtain credentials that can be used for further compromise of the charging station system.

MitigationImplement authentication requirements on all Pile API endpoints to prevent unauthorized access to sensitive information. Restrict network exposure of the charging station management interface and monitor for unauthorized access attempts.

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 charging station firmware version
    Access the station admin interface or API and retrieve the firmware version information. This is typically found in the device status or system settings page.
    Affected if The installed firmware version is below 1.39.51, or falls between 1.39.51 and 1.56.51 inclusive. Firmware versions 1.39.51 and 1.56.51 and above are not affected.
  2. Verify network exposure of the Pile API
    From a network perspective, attempt to reach the Pile API endpoints (typically on port 80/443 or the station's web service port) from an unauthenticated network perspective. Check if the device management interface is exposed to untrusted networks.
    Affected if The charging station management interface or Pile API endpoints are accessible from an untrusted network without any authentication required.
  3. Test for missing authentication on API endpoints
    Send an HTTP GET request to common Pile API endpoints without providing any authentication headers or credentials. Observe if the request returns sensitive data such as credentials or system information.
    Affected if The API responds with sensitive information or credentials without requiring any authentication token or credentials in the request.
  4. Review access logs for unauthenticated API access
    If available, examine the station's access logs or management system logs for any API calls that were made without authentication tokens, particularly those accessing credential-related endpoints.
    Affected if Logs show API requests to sensitive endpoints that lack authentication tokens or originated from unauthenticated sources.

You are affected if your Autel MaxiCharger device runs firmware version below 1.39.51 or between 1.39.51-1.56.51 AND the Pile API endpoints are network-accessible without authentication.
