Summary

CVE-2024-10914 is a critical-severity Injection (CWE-74) vulnerability in Dlink Dns-320 Firmware. Its CVSS base score is 9.2 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.1% 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 vulnerability identified as CVE-2024-10914 affects D-Link DNS-320, DNS-320LW, DNS-325, and DNS-340L devices up to version 20241028. It resides in the cgi_user_add function within /cgi-bin/account_mgr.cgi?cmd=cgi_user_add, where unsanitized input to the name argument permits OS command injection. The flaw is tracked under CWE-74, CWE-78, and CWE-707 and carries a CVSS 4.0 score of 9.2 reflecting high impact on confidentiality, integrity, and availability when successfully exploited.

An unauthenticated remote attacker can trigger the injection by supplying crafted input to the affected CGI endpoint. Although the attack requires high complexity and is considered difficult to exploit in practice, a publicly disclosed proof-of-concept is available that could allow arbitrary command execution on the device.

The provided references include a detailed technical write-up and VulDB entries but do not describe vendor patches or specific mitigation steps from D-Link. The current EPSS score of 0.9361, with a peak of 0.9399, indicates sustained high exploitation probability since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

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

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Output filtering enforces neutralization properties on data leaving the system.

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

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

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