Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-23968 is a buffer overflow vulnerability (CWE-120) in ChargePoint Home Flex charging stations. The flaw resides in the SrvrToSmSetAutoChnlListMsg function, where user-supplied data length is not properly validated before being copied into a fixed-length stack-based buffer. This issue enables network-adjacent attackers to execute arbitrary code without authentication, earning a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Network-adjacent attackers can exploit this vulnerability by sending crafted packets to the affected charging station. No privileges or user interaction are required, allowing remote code execution in the context of root. This grants full control over the device, with high impacts on confidentiality, integrity, and availability.
