Command Injection in Chargepoint Home Flex Nema 14-50 Plug Firmware
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-2024-23971 is a high-severity Command Injection (CWE-77) vulnerability in Chargepoint Home Flex Nema 14-50 Plug Firmware. Its CVSS base score is 8.8 (High).
Operationally, ranked at the 41th 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-2024-23971 is a command injection vulnerability (CWE-77) affecting ChargePoint Home Flex charging stations. The flaw resides in the handling of OCPP messages, where a user-supplied string lacks proper validation before being passed to a system call. This enables network-adjacent attackers to execute arbitrary code in the context of root without requiring authentication.
Network-adjacent attackers can exploit the vulnerability with low complexity, no privileges, and no user interaction, as indicated by the CVSS vector AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (score 8.8). Successful exploitation allows full arbitrary code execution as root, potentially compromising the device's confidentiality, integrity, and availability.
The Zero Day Initiative advisory at https://www.zerodayinitiative.com/advisories/ZDI-24-1053/ provides further details on the issue, including potential mitigation guidance.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover command-construction flaws before deployment.
Input validation directly stops construction of commands from untrusted data containing special elements.
Secure engineering principles include proper neutralization and safe command construction practices.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reduce command injection defects, but leaves a minority slice (e.g. incomplete implementation of those practices, outsourced development without full assurance, or post-SDLC changes) where the weakness can still arise and be exploitable.
Application security requirements explicitly call for controls against injection flaws including command injection.
A.8.27 mandates security-by-design principles (e.g. distrust external input, secure session control, data validation/sanitization, least privilege) and design reviews that can stop command injection from being introduced, but this is only a minority slice of CWE-77 because the weakness can still arise in code that bypasses those principles, in non-reviewed components, or in runtime injection vectors the architecture review does not reach.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
