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.
Solution:
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
