Attack-Flow Graph

Executive Summary

This vulnerability involves two hidden privileged accounts in Autel Maxi Charger Single firmware up to V1.03.51. These accounts use a vendor-specific password system based on device-specific values, allowing attackers who know the algorithm and inputs to gain admin access to the web management interface.

Impact Analysis

An attacker could exploit this to gain full administrative control over the charging device, potentially allowing them to manipulate charging operations, access sensitive data, or disrupt services.

Mitigation Strategies

Update the Autel Maxi Charger Single firmware to the latest version to remove the undocumented privileged accounts. If an update is not available, contact Autel support for assistance. Disable remote access to the web management interface if not required.
