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 ECE could allow an unauthenticated, remote attacker to conduct an XSS attack against a user of the interface of an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious script code in a chat window. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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 confidence

This is a stored Cross-Site Scripting (XSS) vulnerability in Cisco Enterprise Chat and Email (ECE) web-based management interface. The application fails to properly validate user-supplied input in the chat window, allowing an unauthenticated attacker to inject malicious script code that executes in the browsers of other users viewing the chat.

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 ECE is installed
    Check your system for Cisco Enterprise Chat and Email by reviewing installed software packages, looking for ECE service processes, or checking for the ECE web application directory in your web server root.
    Affected if Cisco Enterprise Chat and Email software is present on the system
  2. Determine the installed version of Cisco ECE
    Access the ECE web-based management interface and navigate to the About or System Information section, or check the version file in the ECE installation directory if accessible via command line.
    Affected if The installed version is lower than 12.6(1)es1
  3. Verify the web management interface is accessible
    Attempt to access the ECE web interface by browsing to the host URL and port (typically HTTPS on port 8443 or similar). Confirm the login page or chat window loads.
    Affected if The web interface is reachable and the system is running
  4. Check if chat functionality is enabled
    Log into the ECE web interface and navigate to the chat configuration or agent desktop area. Verify whether the chat window component is active and accessible to users.
    Affected if The chat window feature is enabled and accessible to users
  5. Inspect chat input fields for XSS filtering
    Using an authenticated session as an agent or administrator, observe the chat window. Note whether the application appears to sanitize or reject special characters (such as <, >, script tags) in user-supplied chat messages.
    Affected if The application does not appear to properly sanitize input in the chat window

The environment is affected if Cisco Enterprise Chat and Email is installed with a version lower than 12.6(1)es1 and the web-based chat interface is accessible and enabled.
