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 Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device. 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

This is a reflected cross-site scripting (XSS) vulnerability in the web-based management interfaces of Cisco Prime Infrastructure and Cisco Evolved Programmable Network (EPN) Manager. The interface fails to properly validate user-supplied input, allowing an attacker to embed malicious JavaScript in a crafted link. When a user clicks the link, the script executes in the context of the affected interface, potentially stealing session cookies or performing actions on behalf of the user.

MitigationApply the vendor-supplied patch when available. In the interim, users should avoid clicking untrusted links and organizations may consider restricting web management interface exposure to trusted networks only.

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 installed product
    Determine whether Cisco Evolved Programmable Network (EPN) Manager or Cisco Prime Infrastructure is deployed in your environment. Check installed software listings or consult system documentation.
    Affected if Either product is installed
  2. Check EPN Manager version
    Access the EPN Manager web interface, then navigate to Administration > Software Updates > Installed Software, or run 'show version' via CLI. Record the exact version number.
    Affected if Version is less than 6.0 (for example, 5.x)
  3. Check Prime Infrastructure version
    Access the Prime Infrastructure web interface, then go to Administration > Software Updates > Installed Software, or run 'show version' via CLI. Record the exact version number.
    Affected if Version is less than 3.10 (for example, 3.9.x or earlier)
  4. Assess web interface exposure
    Determine if the web-based management interface is accessible from untrusted networks. Review firewall rules, ACLs, and VPN policies that control access to port 443 or the management web port.
    Affected if Interface is reachable from untrusted or public networks without proper access controls

You are affected if either EPN Manager version is below 6.0 or Prime Infrastructure version is below 3.10, and the web management interface is accessible to users who could click crafted links.

Interim mitigation

Apply the vendor-supplied patch when available. In the interim, users should avoid clicking untrusted links and organizations may consider restricting web management interface exposure to trusted networks only.

Recommended fix High confidence

Prime Infrastructure: 3.10 or later; Evolved Programmable Network Manager: 6.0 or later

  1. 1. Identify the currently installed version of Cisco Prime Infrastructure or Evolved Programmable Network Manager
  2. 2. If running Prime Infrastructure, upgrade to version 3.10 or later
  3. 3. If running Evolved Programmable Network Manager, upgrade to version 6.0 or later
  4. 4. Verify the upgrade was successful by checking the software version in the web-based management interface
  5. 5. Test that the web interface functions normally after upgrade
