Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/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-2023-31700 is a high-severity Command Injection (CWE-77) vulnerability in Tp-Link Tl-Wpa4530 Kit Firmware. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 16% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
TP-Link TL-WPA4530 KIT V2 devices running firmware versions (EU)_170406 and (EU)_161115 contain a command-injection vulnerability (CWE-77) reachable through the _httpRpmPlcDeviceAdd handler. The flaw permits an attacker to supply crafted input that is passed directly to a system command, resulting in arbitrary command execution on the affected powerline adapter.
An authenticated user with network access can exploit the issue without user interaction. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the device, consistent with the CVSS 8.8 rating.
The associated EPSS score stands at 0.1187 with no material increase after disclosure. Public technical details are limited to a single GitHub proof-of-concept report describing the injection point; no vendor advisory or firmware patch information is referenced in the available sources.

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.
