CVE-2020-3185
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 web-based management interface of Cisco TelePresence Management Suite (TMS) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface. The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data in a specific data field in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web-based management interface or access sensitive, browser-based 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 Cisco TelePresence Management Suite is installedLocate the TMS software on the system. Common paths: Windows: C:\Program Files\Cisco Systems\TMS\ or Linux: /opt/cisco/tms/. Check for running process 'TMS' or 'Tomcat' (used by TMS web interface).Affected if The software is present and running on the system.
-
Identify the installed TMS versionAccess the web management interface at https://<tms-host>/tms or check version file at C:\Program Files\Cisco Systems\TMS\version.properties (Windows) or /opt/cisco/tms/version (Linux). Alternatively, log into TMS admin pages and check System > About or Help > About.Affected if The installed version is 15.9 or any version lower than 15.9.
-
Verify the web-based management interface is enabledConfirm the TMS web service is running by accessing https://<tms-host>/tms in a browser or checking that port 443 (or configured HTTPS port) is listening via 'netstat -an | findstr :443' or 'ss -tlnp | grep 443'.Affected if The web interface is accessible and accepts authentication.
-
Confirm TMS administrator accounts existSince this is an authenticated XSS, verify that user accounts with web interface access are configured. Check via TMS admin console under Administration > User Administration, or check local Windows/AD groups authorized for TMS access.Affected if At least one authenticated user account has access to the web management interface.
You are affected if Cisco TelePresence Management Suite is installed with a version of 15.9 or lower and the web-based management interface is accessible with at least one authenticated user.

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 dataImplement proper input validation and output encoding for all user-supplied data fields in the web interface. Apply context-appropriate sanitization (HTML encoding, JavaScript escaping) before rendering user input.
