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

This is an information disclosure vulnerability in the Autel MaxiCharger AC Wallbox Commercial EV chargers. The Autel Technician API contains an exposed dangerous method that allows authenticated remote attackers to disclose sensitive information, specifically credentials. The vulnerability requires authentication to exploit but can lead to further system compromise.

MitigationRestrict access to the Autel Technician API and implement proper authentication and authorization controls. Contact Autel for available patches and ensure the device firmware is updated once available. Network segmentation can also limit exposure.

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 the Autel charger model
    Locate the device label on the charger unit or access the charger web interface to view the model information (e.g., MaxiCharger AC Elite Business C50, AC Pro, AC Ultra, DC Compact, DC Fast, DC Hipower, or DH480)
    Affected if The model is one of the affected products listed in the CVE (C50, AC Pro, AC Ultra, DC Compact Mobile, DC Compact Pedestal, DC Fast, DC Hipower, or DH480)
  2. Check the installed firmware version
    Access the charger administrative web interface and navigate to System Settings or Device Information to view the firmware version. Alternatively, query the device API for firmware version information
    Affected if The firmware version is below 1.39.51 or below 1.56.51 (both thresholds indicate vulnerability)

A user is affected if their Autel MaxiCharger is one of the affected models and is running firmware versions below 1.39.51 or 1.56.51 with the Autel Technician API accessible to network attackers

Upgrade available Upgrade to 1.39.51 / 1.56.51 or later
Fixed in 1.39.511.56.51
Interim mitigation

Restrict access to the Autel Technician API and implement proper authentication and authorization controls. Contact Autel for available patches and ensure the device firmware is updated once available. Network segmentation can also limit exposure.

Recommended fix Moderate confidence

Firmware version 1.39.51 or 1.56.51 (or latest stable release)

  1. Verify current firmware version on the affected Autel MaxiCharger device through the admin interface or device settings
  2. Contact Autel Energy technical support to obtain the firmware update to version 1.39.51 or 1.56.51 (or latest stable release)
  3. Review Autel Energy's official security advisory or release notes for the firmware update
  4. Download the firmware update from Autel Energy's official support portal or obtain directly from vendor
  5. Apply the firmware update following Autel's standard update procedure, typically via the device's web interface or dedicated management software
  6. After update, verify the Autel Technician API no longer exposes dangerous methods and credentials cannot be disclosed
  7. Confirm the new firmware version is 1.39.51 or higher, or 1.56.51 or higher
