CVE-2025-5828

Code execution via unchecked USB packet length

Published Jun 25, 2025 · Updated Jun 26, 2025

A buffer overflow in Autel MaxiCharger AC Wallbox Commercial 1.36.00 allows physically proximate attackers to execute code via USB packets. The USB frame handler copies user-supplied data into a fixed-length buffer without first validating the packet's wLength value. Exploitation requires physical access but no authentication and executes code in the context of the charging device.
