Description

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex charging stations. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SrvrToSmSetAutoChnlListMsg function. 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.

Analysis

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex charging stations. Rated high severity (CVSS 8.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.

Technical Context

This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex charging stations. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SrvrToSmSetAutoChnlListMsg function. 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. Affected products include: Chargepoint Home Flex Nema 14-50 Plug Firmware, Chargepoint Home Flex Hardwired Firmware, Chargepoint Home Flex Nema 6-50 Plug Firmware.
