CVE-2022-29499
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 · uneditedThe Service Appliance component in Mitel MiVoice Connect through 19.2 SP3 allows remote code execution because of incorrect data validation. The Service Appliances are SA 100, SA 400, and Virtual SA.
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 confidenceMitel MiVoice Connect Service Appliances (SA 100, SA 400, and Virtual SA) through version 19.2 SP3 contain a data validation flaw allowing unauthenticated remote attackers to execute arbitrary code. The critical severity (CVSS 9.8) indicates the vulnerability is trivially exploitable over the network without credentials.

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.
-
Confirm MiVoice Connect installation and versionCheck the installed MiVoice Connect version by accessing the system administration interface or using the built-in version check command/tool provided by Mitel. Compare the version number against the affected range (<= 22.20.2300.0).Affected if The installed version is 22.20.2300.0 or lower, or the system reports a version within the 19.x through 22.x range indicating it is before the fix.
-
Identify Service Appliance modelDetermine whether the deployed device is an SA 100, SA 400, or Virtual SA appliance by checking the system information in the appliance admin console or hardware labeling.Affected if The device is identified as an SA 100, SA 400, or Virtual SA appliance running a vulnerable MiVoice Connect version.
-
Verify Service Appliance component is enabledAccess the MiVoice Connect administration interface and check whether the Service Appliance component is actively enabled or running on the system.Affected if The Service Appliance component is enabled and running on the target system.
-
Assess network accessibilityDetermine if the Service Appliance management interface or associated service ports are accessible from untrusted networks by reviewing firewall rules, exposed network interfaces, and external access controls.Affected if The Service Appliance is reachable from network segments that are not restricted to trusted IPs only, allowing unauthenticated network attackers to reach the vulnerable component.
A user is affected if MiVoice Connect version 22.20.2300.0 or lower is installed on an SA 100, SA 400, or Virtual SA appliance with the Service Appliance component enabled and exposed to untrusted networks.

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.
dbcve · scopedApply the vendor-provided patch or upgrade to a MiVoice Connect version beyond 19.2 SP3. If patching is immediately unfeasible, restrict network access to the Service Appliance management interfaces via firewall rules or VLAN isolation.
Mitel MiVoice Connect version greater than 22.20.2300.0 or a version beyond 19.2 SP3 as specified in Mitel's official security advisory
- 1. Identify the current version of Mitel MiVoice Connect by accessing the SA 100, SA 400, or Virtual SA appliance administration interface
- 2. Navigate to the system information or about section to confirm the exact version number
- 3. Contact Mitel support or check the official Mitel security advisory page for the specific fixed version addressing CVE-2022-29499
- 4. Obtain the upgrade package from Mitel's official support portal or authorized distribution channels
