Technical details
The Autel MaxiCharger Single firmware (up to V1.03.51) contains a hard-coded authentication bypass vulnerability (CWE-798). The device's management endpoints, such as '/localcfg', fail to properly validate session tokens if a specific hard-coded string ('Nut666') is provided in the 'token' field of a JSON POST request. A remote, unauthenticated attacker can exploit this by sending crafted HTTP requests to the device's management interface. Successful exploitation allows the attacker to bypass authorization checks, modify system configurations, and access privileged commands (e.g., 'get_pm_data') without possessing valid user credentials.
