Description
Autel MaxiCharger AC Elite Home WebSockets Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of WebSocket messages related to the OCPP service. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-29113.
