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 · unedited
A vulnerability in the web-based management interface of Cisco TelePresence Management Suite (TMS) could allow a low-privileged, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This 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 interface or access sensitive, browser-based 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 confidence

A stored cross-site scripting (XSS) vulnerability exists in Cisco TelePresence Management Suite web interface where low-privileged users can inject malicious script code through insufficiently validated input fields, potentially executing arbitrary JavaScript in other users' browser sessions.

MitigationApply Cisco's patch when available; implement proper input validation and output encoding on affected data fields, and restrict TMS administrative access to reduce attack surface until patch is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Cisco TelePresence Management Suite is installed
    Check your systems for the presence of Cisco TMS software. Common installation locations on Windows may be under C:\Program Files\Cisco\ or check for the TMS service using 'services.msc' or 'sc query' command.
    Affected if Cisco TelePresence Management Suite software is found on the system
  2. Determine the installed TMS version
    Access the TMS web interface and navigate to Administration > System Settings > TMS Server Information, or check the installed programs list in Windows Control Panel, or run 'tmssetup -version' if available from command line.
    Affected if The installed version is 15.13.5, 15.13.6, or any version >= 15.13.5 but < 15.13.7
  3. Verify the TMS web interface is accessible
    Attempt to access the TMS web interface via browser at the configured URL (commonly https://hostname/tms or port 443). Confirm the service is running by checking the TMS service status in Windows Services or via 'net start' command.
    Affected if The TMS web interface is reachable and accepts authentication
  4. Confirm presence of low-privileged user accounts
    Log into TMS with administrator credentials and review User Administration to list all configured users and their permission levels. Check for non-admin accounts with 'User' or 'Guest' level access.
    Affected if Low-privileged user accounts (non-administrator) exist in the TMS user database

You are affected if Cisco TelePresence Management Suite is installed with version 15.13.5 through 15.13.6, the web interface is enabled, and low-privileged users have access to input fields that can be exploited for stored XSS.

Interim mitigation

Apply Cisco's patch when available; implement proper input validation and output encoding on affected data fields, and restrict TMS administrative access to reduce attack surface until patch is applied.

Recommended fix High confidence

15.13.7 or later

  1. 1. Identify the current version of Cisco TelePresence Management Suite (TMS) by checking the About or System Information page in the web-based management interface
  2. 2. Schedule a maintenance window for the upgrade process
  3. 3. Back up the TMS configuration data according to Cisco backup procedures
  4. 4. Download the fixed TMS version 15.13.7 or later from the Cisco software downloads page
  5. 5. Apply the upgrade following Cisco's standard TMS upgrade documentation
  6. 6. Verify the upgrade was successful by checking the TMS version in the web-based management interface
  7. 7. Test that the web-based management interface functions normally after the upgrade
