CVE-2025-5830

Adjacent-network code execution via DLB_SlaveRegister heap overflow

Published Jun 25, 2025 · Updated Jun 26, 2025

Heap-based buffer overflow in Autel MaxiCharger AC Wallbox Commercial 1.36.00 allows network-adjacent attackers to execute code. The DLB_SlaveRegister handler copies attacker-controlled data into a fixed-length heap buffer without first validating its length. No authentication or user interaction is required, and successful exploitation executes code in the device context.
