Description

Autel MaxiCharger AC Elite Business C50 DLB_HostHeartBeat Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Business C50 charging stations. Authentication is not required to exploit this vulnerability.<br /> <br /> The specific flaw exists within the DLB_HostHeartBeat handler of the DLB protocol implementation. When parsing an AES key, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
