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 Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by injecting malicious code into specific pages of 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. To exploit this vulnerability, the attacker would need valid credentials to access the web-based management interface of an affected device.

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

Cross-site scripting (XSS) vulnerability in Cisco Identity Services Engine web-based management interface due to insufficient validation of user-supplied input. An authenticated attacker can inject malicious script code into specific pages, enabling execution of arbitrary scripts in the context of the affected interface or access to sensitive browser-based information.

MitigationApply the Cisco ISE patch when available; until then, enforce least-privilege access to the web management interface and monitor for suspicious administrative activity.

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 ISE version
    Access the Cisco ISE administrative interface and navigate to Administration > System > Settings > General Setup, or use the CLI command 'show version' to determine the installed Cisco ISE version.
    Affected if The installed version is less than 2.7.0, or exactly 2.7.0, 3.0.0, or 3.1.
  2. Confirm web management interface is accessible
    Verify that the Cisco ISE web-based management interface is reachable and operational. This is typically accessible via HTTPS on port 443 or 8443.
    Affected if The web-based management interface is enabled and accessible (the XSS flaw exists within this interface).
  3. Review admin user access
    Check if there are any user accounts with administrative privileges configured in Cisco ISE. The vulnerability requires an authenticated attacker.
    Affected if Administrative or privileged user accounts exist in the system, as the vulnerability is exploitable by authenticated users.

A user is affected if their Cisco ISE version matches less than 2.7.0, exactly 2.7.0, exactly 3.0.0, or exactly 3.1, and the web-based management interface is accessible to authenticated users.

Upgrade available Upgrade to 2.7.0 or later
Fixed in 2.7.0
Interim mitigation

Apply the Cisco ISE patch when available; until then, enforce least-privilege access to the web management interface and monitor for suspicious administrative activity.

Recommended fix Moderate confidence

Cisco ISE 3.2 or later (verify latest available version on Cisco.com)

  1. 1. Log into the Cisco Identity Services Engine admin interface
  2. 2. Navigate to Administration > System > Software Updates > Software Updates
  3. 3. Check current software version under Administration > System > Licensing > Product License Status
  4. 4. Download the fixed version (3.2 or later) from Cisco.com Software Download center
  5. 5. Create a backup of the ISE configuration under Administration > System > Backup & Restore > Configuration Backup
  6. 6. Schedule a maintenance window as upgrade requires system restart
  7. 7. Upload the new software image and initiate upgrade following the migration guide
  8. 8. Verify upgrade completion and confirm version under Administration > System > About Cisco ISE
Caveat Upgrade may require ISE restart causing temporary service interruption; ensure configuration compatibility and review release notes for migration considerations
