CVE-2025-9387
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in DCN DCME-720 9.1.5.11. This affects an unknown function of the file /usr/local/www/function/audit/newstatistics/ip_block.php of the component Web Management Backend. Performing manipulation of the argument ip results in os command injection. It is possible to initiate the 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOS command injection vulnerability in DCN DCME-720 Web Management Backend allows remote attackers to execute arbitrary operating system commands via manipulation of the 'ip' parameter in /usr/local/www/function/audit/newstatistics/ip_block.php. The vulnerable component fails to properly sanitize user input before passing it to system command execution functions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device console or web interface and confirm the model is DCME-720 (or Dcnetworks DCME-720)Affected if The device is not a DCN DCME-720 unit
-
Check the firmware versionNavigate to the web management backend System Settings or Firmware Info page, or run 'ver' or 'show version' command via console to identify the installed firmware versionAffected if The firmware version is 9.1.5.11
-
Verify the vulnerable file existsCheck if the file /usr/local/www/function/audit/newstatistics/ip_block.php exists on the device filesystem (via SSH/console access or by attempting to access the URL directly)Affected if The file exists on the system
-
Confirm web management interface is accessibleAttempt to access the device web management interface via HTTP/HTTPS on the management port (typically 80 or 443)Affected if The web management interface is reachable over the network
-
Test the vulnerable endpoint accessibilityAttempt to access the URL path /function/audit/newstatistics/ip_block.php via the web interface or check if the endpoint respondsAffected if The endpoint is accessible and processes the 'ip' parameter
If the device is a DCN DCME-720 running firmware version 9.1.5.11 with the web management interface exposed and the ip_block.php endpoint accessible, the environment is affected by this command injection vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and use parameterized APIs or escaping functions for any system calls. If possible, restrict network access to the management interface or disable the vulnerable function until a vendor patch is available.
