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 Unified Intelligence Center Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. 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 · high confidence

A cross-site scripting (XSS) vulnerability exists in Cisco Unified Intelligence Center's web-based management interface due to improper validation of user-supplied input. An unauthenticated remote attacker can exploit this by tricking a user into clicking a crafted link, allowing execution of arbitrary script code in the context of the affected interface or access to sensitive browser-based information.

MitigationApply the vendor patch or upgrade to a fixed Cisco Unified Intelligence Center Software version as specified in Cisco's security advisory. Educate users about avoiding clicking suspicious links as a defense-in-depth measure.

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 Cisco Unified Intelligence Center or Unified Contact Center Express installation
    Check if the web-based management interface is accessible by attempting to reach the application login page (typically https://<hostname>/cuic or the Unified CCX web interface). If no web interface responds, the vulnerability may not be applicable.
    Affected if The web management interface is accessible and the product is Cisco Unified Intelligence Center or Cisco Unified Contact Center Express.
  2. Determine the installed software version
    Log into the web-based management interface and navigate to the About or System Information page to view the software version. Alternatively, access the server via SSH and use CLI commands such as 'show version' or 'utils system version' to retrieve the version information.
    Affected if Unable to retrieve version information from the web interface or CLI.
  3. Compare against affected version ranges
    Match the retrieved version number against the affected ranges: For Cisco Unified Contact Center Express: versions <= 12.0(1) OR >= 12.5(1) but < 12.5(1)su1 are affected. For Cisco Unified Intelligence Center: versions <= 11.6(1) OR >= 12.0(1) but < 12.0(1)es14 OR >= 12.5(1) but < 12.5(1)es7 are affected.
    Affected if The installed version falls within any of the listed affected ranges.
  4. Verify web interface accessibility
    Confirm that the web-based management interface is exposed to network traffic. Check if the interface is reachable from network segments accessible to users who might click crafted links.
    Affected if The web management interface is externally accessible or accessible to untrusted users without authentication.

If the installed Cisco Unified Intelligence Center or Unified Contact Center Express version falls within the affected ranges and the web management interface is accessible, the environment is potentially affected by this XSS vulnerability.
