Likely Mitigating ControlsAI

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.

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.

addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

The vulnerability is a remote OS command injection in the web management backend (/usr/local/www/function/audit/newstatistics/ip_block.php), enabling exploitation of a public-facing web application (T1190) and execution of Unix shell commands via tainted input (T1059.004).

attack remotely. The exploit has been made public and could be used. Other products might be affected as well. The vendor was contacted early about this disclosure but did not respond in any way.

Deeper analysisAI

CVE-2025-9387 is an OS command injection vulnerability (CWE-77, CWE-78) in DCN DCME-720 version 9.1.5.11. It affects an unknown function within the file /usr/local/www/function/audit/newstatistics/ip_block.php of the Web Management Backend component. The flaw occurs through manipulation of the 'ip' argument, enabling injection and execution of arbitrary operating system commands.

The vulnerability is remotely exploitable over the network with low attack complexity, requiring low privileges but no user interaction (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L, score 6.3 Medium). Attackers with such access can achieve limited impacts on confidentiality, integrity, and availability, including execution of OS commands on the affected system.

Advisories from VulDB and a GitHub repository (lin-3-start/lin-cve) detail the issue, including a publicly available proof-of-concept exploit with verification steps. The vendor was contacted early regarding disclosure but provided no response, and no patches or mitigations are mentioned. Other products may also be affected.

A proof-of-concept exploit has been made public and could be used in attacks.
