Authentication bypass via hardcoded BLE fallback credentials
Published Sep 28, 2024 · Updated Oct 3, 2024
Authentication bypass in Autel MaxiCharger AC Elite Business C50 1.32.00 allows attackers to gain unauthorized control over BLE. The AppAuthenRequest handler substitutes hardcoded credentials when a BLE authentication request fails, accepting a shared fallback instead of rejecting the request. No authentication or user interaction is required, but the attacker must be within BLE range; the documented consequence is unauthorized system modification.
