CVE-2020-25611
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 AWV portal of Mitel MiCollab before 9.2 could allow an attacker to gain access to conference information by sending arbitrary code due to improper input validation, aka XSS. Successful exploitation could allow an attacker to view user conference information.
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 confidenceCross-site scripting (XSS) vulnerability in the AWV portal of Mitel MiCollab versions before 9.2 allows attackers to inject arbitrary JavaScript code through improper input validation. This enables attackers to execute malicious scripts in the context of the application to view user conference information.

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 MiCollab installationLocate the Mitel MiCollab installation in your environment and identify the installed version number. This is typically available through the system administration console, software inventory, or by querying the MiCollab server directly.Affected if MiCollab is installed and the version is below 9.2 (e.g., 9.0, 8.x, earlier versions)
-
Verify AWV portal is enabledCheck if the AWV (Advanced Web Viewer) portal component is enabled and accessible in your MiCollab deployment. This is typically configured in the MiCollab administration interface under portal or web service settings.Affected if The AWV portal is enabled and exposed to users, as the XSS vulnerability exists specifically within this component
-
Confirm network accessibility of AWV portalDetermine if the AWV portal is reachable from user networks or the internet. Check firewall rules, reverse proxy configurations, and access control lists that govern access to the MiCollab web interfaces.Affected if The AWV portal is accessible to users who could potentially inject malicious scripts, as the vulnerability is exploited through user-supplied input to this portal
Your environment is affected if Mitel MiCollab is installed with a version lower than 9.2 AND the AWV portal is enabled and accessible to users who can supply input to it.

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 data9.2
Implement proper input validation and output encoding/sanitization on all user-supplied data in the AWV portal. Upgrade to MiCollab version 9.2 or later which contains the fix.
