CVE-2022-41326
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 web conferencing component of Mitel MiCollab through 9.6.0.13 could allow an unauthenticated attacker to upload arbitrary scripts due to improper authorization controls. A successful exploit could allow remote code execution within the context of the application.
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 confidenceMitel MiCollab web conferencing component through 9.6.0.13 contains improper authorization controls that allow unauthenticated attackers to upload arbitrary scripts. This authorization bypass enables remote code execution within the application context.

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 MiCollab installationCheck for MiCollab installation directories (commonly under C:\Program Files\Mitel\MiCollab or /opt/mitel/micollab) or look for the MiCollab service running on the systemAffected if MiCollab software is present on the system
-
Determine installed MiCollab versionLocate the version information in the application's about page, installation logs, or version file (typically in the main MiCollab directory or registry under HKLM\SOFTWARE\Mitel\MiCollab)Affected if The installed version is 9.6.0.105 or lower
-
Verify web conferencing component is accessibleConfirm the MiCollab web interface (typically ports 80/443 or 8080/8443) is exposed and reachable on the networkAffected if The web conferencing component is accessible without authentication and accepts file uploads
-
Confirm file upload functionality is exposedInspect the web application's upload endpoints (usually under /ucm/, /fileupload/, or similar paths in the MiCollab web conferencing portal)Affected if The upload functionality can be accessed without authentication or proper authorization checks
The environment is affected if MiCollab version 9.6.0.105 or lower is installed and the web conferencing component with file upload functionality is accessible.
