Summary

CVE-2024-41473 is a critical-severity OS Command Injection (CWE-78) vulnerability in Tendacn Fh1201 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Tenda FH1201 version 1.2.0.14 contains a command injection vulnerability, tracked as CVE-2024-41473 and assigned CWE-78, in the mac parameter processed by the ip/goform/WriteFacMac endpoint. The flaw received a CVSS 3.1 score of 9.8, driven by its network attack vector, lack of required authentication or user interaction, and full impact on confidentiality, integrity, and availability.

Unauthenticated remote attackers can supply crafted input to the affected endpoint and execute arbitrary operating-system commands on the router. This grants complete device compromise, enabling actions such as configuration changes, traffic interception, or persistence mechanisms.

The two referenced GitHub repositories document the vulnerability through proof-of-concept details but contain no vendor advisories, firmware patches, or mitigation steps.

The CVE maintains a high EPSS score, recorded at 0.8630 currently with a peak of 0.8798.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

SI-10 Information Input Validation good match

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

AC-6 Least Privilege partial match

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

CM-7 Least Functionality partial match

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
