Description
Autel MaxiCharger AC Wallbox Commercial DLB_SlaveRegister Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Wallbox Commercial EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DLB_SlaveRegister messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26327.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a heap-based buffer overflow in the Autel MaxiCharger AC Wallbox Commercial EV chargers. It occurs because the device does not properly validate the length of user-supplied data in DLB_SlaveRegister messages before copying it into a fixed-length heap buffer. This flaw allows network-adjacent attackers to execute arbitrary code on the device without needing authentication. [1]


How can this vulnerability impact me? :

Exploiting this vulnerability allows attackers to execute arbitrary code on the affected device with its privileges. This can lead to compromise of the device's confidentiality, integrity, and availability, potentially allowing attackers to control or disrupt the EV charger. [1]
