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 Unix Shell (T1059.004); ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

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

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.
