Summary

CVE-2024-9916 is a medium-severity OS Command Injection (CWE-78) vulnerability in Usualtool Usualtoolcms. Its CVSS base score is 6.9 (Medium).

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

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, identified as CVE-2024-9916 and assigned CWE-78, affects HuangDou UTCMS V9. The flaw resides in an unknown function within the file app/modules/ut-cac/admin/cli.php, where unsanitized input to the argument o permits arbitrary operating system command execution.

Remote attackers can exploit the issue without authentication or user interaction by sending crafted requests to the affected endpoint. Successful exploitation grants the ability to execute commands on the underlying system, resulting in limited impacts to confidentiality, integrity, and availability as reflected in the CVSS 4.0 vector.

Public exploit details have been disclosed via repositories and vulnerability databases, and the vendor was notified prior to publication but provided no response or patch. The associated EPSS score currently stands at 0.8357 with a recorded peak of 0.8510, indicating sustained but not sharply escalating exploitation interest since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

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

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

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.

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).
