CVE-2023-31457
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 in the Headquarters server component of Mitel MiVoice Connect versions 19.3 SP2 (22.24.1500.0) and earlier could allow an unauthenticated attacker with internal network access to execute arbitrary scripts due to improper access control.
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.

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 Mitel MiVoice Connect installationCheck system inventory or installed programs for Mitel MiVoice Connect presence. On Windows, inspect Add/Remove Programs or the installation directory typically located at C:\Program Files\Mitel\ or C:\Mitel. On Linux, check common application paths or package manager listings.Affected if Mitel MiVoice Connect software is found on the system
-
Determine installed versionLocate the installed version information. Check the application itself for version details, or look for version files in the installation directory. Common locations include the main executable properties, a version.info file, or within the application's About/Help section.Affected if Installed version is 22.24.1500.0 or earlier, or version 19.3 SP2 or earlier
-
Verify Headquarters server component statusCheck if the Headquarters server component is installed and running. This is typically configured in the Mitel service management console, Windows Services panel, or the MiVoice Connect administration interface. Look for services named 'Mitel MiVoice Connect' or 'Headquarters' or 'MQG' related services.Affected if Headquarters server component is installed and enabled
-
Check network accessibility of Headquarters serviceExamine network listeners and firewall rules to determine if the Headquarters service port is exposed to the internal network. Common ports include 8080, 8443, or 443. Use netstat -an or equivalent to identify listening ports associated with the Mitel services.Affected if Headquarters service port is listening and accessible from internal network without authentication barriers
A system is affected if it runs Mitel MiVoice Connect version 22.24.1500.0 or earlier with the Headquarters server component enabled and exposed to the internal network, allowing unauthenticated access.

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 dataUpgrade Mitel MiVoice Connect to a patched version beyond 19.3 SP2 (22.24.1500.0) and enforce network segmentation to limit internal attack surface.
