CVE-2025-5827

Unauthenticated code execution via unchecked BLE message length

Published Jun 25, 2025 · Updated Jun 26, 2025

Stack-based buffer overflow in Autel MaxiCharger AC Wallbox Commercial 1.36.00 allows remote attackers to execute code over Bluetooth. The ble_process_esp32_msg function copies user-supplied data into a fixed-length stack buffer without validating its length. An unauthenticated attacker within Bluetooth range can execute code in the device firmware without user interaction.
