ChargePoint Home Flex OCPP getpreq Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of OCPP 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 stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26339.
Analysis
Stack-based buffer overflow in ChargePoint Home Flex electric vehicle chargers enables network-adjacent attackers to execute arbitrary code as root via malformed OCPP messages. Unauthenticated exploitation allows complete device compromise through improper length validation in OCPP getpreq message handling. …
