CVE-2024-23959

Code execution via AppChargingControl stack buffer overflow

Published Sep 28, 2024 · Updated Oct 3, 2024

Stack-based buffer overflow in Autel MaxiCharger AC Elite Business C50 1.32.00 allows remote authenticated users to execute code via BLE. The AppChargingControl handler copies attacker-supplied data into a fixed-length stack buffer without first validating its length. An authentication bypass exposes the command to network-adjacent attackers, and successful exploitation runs code in the device context.
