Raw vector
CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-23921 is a high-severity Code Injection (CWE-94) vulnerability in Chargepoint Home Flex Nema 14-50 Plug Firmware. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 42th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-23921 is a command injection vulnerability (CWE-94) affecting ChargePoint Home Flex charging stations. The flaw resides in the wlanapp module, where a user-supplied string is not properly validated before being used in a system call. This allows network-adjacent attackers to execute arbitrary code in the context of root without requiring authentication. The vulnerability was published on 2025-01-31 and carries 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, positioned on the same local network as the charging station, can exploit this issue with low complexity and no privileges or user interaction needed. By crafting a malicious string that triggers the flawed system call, an attacker gains remote code execution as root, enabling full control over the device, including potential data exfiltration, modification of configurations, or disruption of charging operations.
The Zero Day Initiative advisory ZDI-24-1049 provides details on the vulnerability. No specific patch or mitigation details are outlined in the available information.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
