Summary

CVE-2024-2897 is a medium-severity OS Command Injection (CWE-78) vulnerability in Tenda Ac7 Firmware. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 6% 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.

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

A critical OS command injection vulnerability, tracked as CVE-2024-2897 and assigned CWE-78, affects the Tenda AC7 wireless router running firmware 15.03.06.44. The flaw resides in the formWriteFacMac function of the /goform/WriteFacMac endpoint, where unsanitized input to the mac parameter is passed directly to the operating system.

An authenticated remote attacker can supply a crafted mac value to execute arbitrary commands on the device. With a CVSS score of 6.3, successful exploitation yields limited read, write, and availability impact on the affected router without requiring user interaction.

Public references, including a detailed proof-of-concept on GitHub and entries in VulDB, document the issue and confirm that the vendor was notified yet provided no response or patch. The associated EPSS score has remained flat at 0.0564 since disclosure, indicating no measurable increase in observed exploitation interest.

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).
