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 could allow an unauthenticated, remote attacker to conduct a reflected 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 the 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

This is a reflected cross-site scripting (XSS) vulnerability in Cisco Unified Intelligence Center's web-based management interface. The vulnerability stems from improper validation of user-supplied input, allowing unauthenticated attackers to inject malicious scripts via crafted links. Successful exploitation enables arbitrary script execution in the context of the affected interface or access to sensitive browser-based information.

MitigationApply the vendor-supplied patch from Cisco. Until patched, users should be cautioned against clicking untrusted links and web application firewalls or URL filtering may provide interim protection.

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 the installed Cisco product
    Log into the system and run 'show version' or check the product documentation to determine if Cisco Unified Intelligence Center, Unified Contact Center Enterprise, Unified Contact Center Express, or Packaged Contact Center Enterprise is installed
    Affected if The product is one of these four affected products
  2. Determine the installed version
    Run 'show version' in the CLI or access the web management interface and navigate to Help > About to retrieve the exact version number (e.g., 12.5(1), 12.6(1))
    Affected if The version falls within the affected ranges: < 12.5(1)_es02, >= 12.5(2) but < 12.6(1)_es06, >= 12.6(1) but < 12.6(1)_es06, or >= 12.5(1)_su2 but < 12.5(1)_su2_es05 depending on the product
  3. Verify web management interface is enabled
    Check if the Cisco Unified Intelligence Center web interface is accessible by attempting to reach the management URL (typically https://<hostname>/cuic) from the network
    Affected if The web-based management interface is exposed and accessible
  4. Confirm XSS attack surface
    Review web server logs for suspicious URL parameters containing script tags or unusual characters in query strings that may indicate exploitation attempts
    Affected if Unusual or malicious parameters are found in HTTP requests to the web interface

If the installed Cisco product version is within the affected ranges and the web management interface is accessible, the environment is vulnerable to reflected XSS attacks via crafted links.

Interim mitigation

Apply the vendor-supplied patch from Cisco. Until patched, users should be cautioned against clicking untrusted links and web application firewalls or URL filtering may provide interim protection.

Recommended fix Moderate confidence

12.5(1)_su2_es05 or 12.6(1)_es06 (depending on current branch)

  1. 1. Identify the current installed version of Cisco Unified Intelligence Center (UIC) by accessing the Administration menu > System > Version
  2. 2. Based on the current version, determine the appropriate upgrade path to reach the fixed release: for 12.5(1) versions upgrade to 12.5(1)_su2_es05 or later; for 12.5(2) and 12.6(1) versions upgrade to 12.6(1)_es06 or later
  3. 3. Review Cisco UCS hardware and software compatibility matrix for your deployment to ensure target version compatibility
  4. 4. Schedule a maintenance window and perform a full backup of the current system including database and configuration
  5. 5. Follow the Cisco Unified Contact Center Express upgrade procedure documentation for your specific version path
  6. 6. Upgrade the system to the minimum fixed version (12.5(1)_su2_es05 for 12.5.x branches, or 12.6(1)_es06 for 12.6.x branches)
  7. 7. After upgrade, verify the system is operational and test that the XSS vulnerability is remediated by confirming the fix is applied
  8. 8. Clear browser cache and validate that the web interface loads correctly
Caveat Upgrades between major releases may require careful planning; ensure compatibility with dependent systems and review Cisco upgrade guides for any migration requirements
