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 · unedited
A vulnerability in the Connect Mobility Router component of Mitel MiVoice Connect through 9.6.2304.102 could allow an authenticated attacker with elevated privileges and internal network access to conduct a command argument injection due to insufficient parameter sanitization. A successful exploit could allow an attacker to access network information and to generate excessive network traffic.

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 · moderate confidence

Command argument injection vulnerability in Mitel MiVoice Connect's Connect Mobility Router (versions through 9.6.2304.102). Authenticated attackers with elevated privileges and internal network access can inject arbitrary commands due to insufficient parameter sanitization, enabling access to network information and generation of excessive network traffic.

MitigationApply Mitel's available patch for MiVoice Connect 9.6.2304.102 or later. Restrict administrative access to the Connect Mobility Router to trusted personnel and implement network segmentation to limit exposure to internal-only attack surface.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm MiVoice Connect installation
    Identify whether Mitel MiVoice Connect software is installed on the system or network appliance. Check installed programs, system inventory, or documentation for presence of this product.
    Affected if MiVoice Connect is found on the system
  2. Determine the installed version
    Locate the version number of the MiVoice Connect installation. Check the application's about dialog, installation directory for version files, or use system inventory tools to retrieve the installed software version.
    Affected if The version is 9.6.2304.102 or any earlier version (any version <= 9.6.2304.102)
  3. Identify Connect Mobility Router component
    Determine whether the Connect Mobility Router component is present and configured in the MiVoice Connect installation. Check the product's administrative interface or component list for this specific module.
    Affected if Connect Mobility Router is installed and active
  4. Verify administrative access exposure
    Assess whether the Connect Mobility Router administrative interface is accessible to network segments beyond trusted personnel. Review access control lists, firewall rules, or network segmentation surrounding the router's management ports.
    Affected if Administrative interface is accessible from broader internal network beyond intended trusted personnel
  5. Check for suspicious activity or configuration changes
    Review Connect Mobility Router logs, configuration files, and network traffic records for unexpected commands, parameter modifications, or unusual network information access patterns that may indicate exploitation.
    Affected if Unusual command parameters, unexpected network information queries, or anomalous traffic patterns are found in logs

A system is affected if MiVoice Connect version 9.6.2304.102 or earlier is installed with the Connect Mobility Router component enabled and the administrative interface has broader-than-intended internal network access.
