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 Unix Shell (T1059.004); ranked in the top 0.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

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

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
