CVE-2020-25606
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 component of Mitel MiCollab before 9.2 could allow an attacker to view system information by sending arbitrary code due to improper input validation, aka XSS.
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 confidenceThis is a Cross-Site Scripting (XSS) vulnerability in the AWV (Advanced Web Viewer) component of Mitel MiCollab. Due to improper input validation, an unauthenticated attacker can inject malicious JavaScript code through the web interface that executes in the context of other users' sessions, allowing the attacker to view system information and potentially steal session 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 MiCollab installation and versionLocate the MiCollab installation directory or check system inventory for 'Mitel MiCollab'. Retrieve the installed version number from the application itself, its installer, or system package information.Affected if The installed version is below 9.2 (e.g., 9.0, 8.x, 7.x, etc.) or the version cannot be determined but the product is present.
-
Verify AWV component is enabledAccess the MiCollab web administration console and navigate to the Advanced Web Viewer (AWV) component settings. Confirm whether the AWV web interface is enabled and accessible via HTTP/HTTPS.Affected if The AWV component is enabled and exposes a web interface to users or the network.
-
Inspect web access logs for injection attemptsReview the AWV or MiCollab web server access logs for unusual query parameters, form submissions, or URI patterns containing JavaScript tags (<script>, javascript:, etc.) or HTML elements (onerror, onload, etc.).Affected if Log entries contain unsanitized input with script tags or event handlers in AWV request parameters.
-
Check for unauthorized session activityReview user session logs, authentication logs, or SIEM alerts associated with AWV endpoints for anomalous actions, especially actions performed by users who did not initiate them or actions occurring outside normal business patterns.Affected if There are session anomalies, credential access attempts, or unexpected system information queries originating from AWV.
A user is affected if Mitel MiCollab with AWV component is running and the installed version is below 9.2, or if evidence of script injection exists in AWV-related web traffic or logs.

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
Upgrade Mitel MiCollab to version 9.2 or later which includes proper input validation. Until patched, monitor web traffic for suspicious script injection attempts in AWV endpoints.
