Summary

CVE-2024-44400 is a critical-severity Command Injection (CWE-77) vulnerability in Dlink Di-8400 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 4% 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.

A vulnerability was discovered in DI_8400-16.07.26A1, classified as critical under CVE-2024-44400. It resides in the upgrade_filter_asp function within upgrade_filter.asp, where manipulation of the path parameter enables command injection. The issue is tracked as CWE-77 and carries a CVSS 3.1 score of 9.8 reflecting network attack vector, low complexity, and no required privileges or user interaction.

Unauthenticated remote attackers can exploit the flaw over the network to inject and execute arbitrary commands, resulting in complete compromise of confidentiality, integrity, and availability on the affected device. The current and peak EPSS score stands at 0.3988 with no material rise indicated after disclosure.

The supplied references consist of GitHub files that document the command-injection vector but contain no information on patches, workarounds, or vendor mitigation guidance.

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

finds

Security testing in development catches command-injection vulnerabilities before release.

prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
