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 obtain sensitive information from an affected device. This vulnerability is due to improper enforcement of administrative privilege levels for high-value sensitive data. An attacker with read-only Administrator privileges to the web-based management interface on an affected device could exploit this vulnerability by browsing to a page that contains sensitive data. A successful exploit could allow the attacker to collect sensitive information regarding the configuration of the system.

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

Cisco ISE web-based management interface fails to properly enforce privilege level restrictions, allowing read-only Administrator accounts to access pages containing highly sensitive system configuration data that should be restricted to higher privilege levels.

MitigationImplement proper role-based access control (RBAC) checks on all pages exposing sensitive configuration data to ensure read-only administrators cannot access high-value sensitive information.

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 installation
    Check if Cisco ISE is deployed in your environment by accessing the web management interface at the configured ISE hostname/IP, or by running 'show version' via SSH/console on the ISE appliance. Cisco ISE typically listens on port 443 for admin access.
    Affected if Cisco ISE is not installed, the vulnerability does not apply.
  2. Determine installed Cisco ISE version
    Log into the ISE web admin portal and navigate to Administration > System > Settings > Product Version to view the exact version, or run 'show version' via CLI.
    Affected if The installed version equals 2.6.0, 2.7.0, 3.0.0, or 3.1 exactly.
  3. Verify web-based management interface is enabled
    Confirm the ISE admin web interface is accessible by attempting to reach the login page at your ISE hostname. The vulnerability requires the web interface to be exposed.
    Affected if The web management interface is disabled or unreachable, the flaw cannot be exploited.
  4. Check for read-only Administrator accounts
    In the ISE web portal, go to Administration > Identity Management > Identities > Users and review account privilege levels, or use CLI 'show running-config | include user' to list configured administrative accounts.
    Affected if No read-only Administrator accounts exist, the privilege escalation vector is not present.

You are affected if Cisco ISE versions 2.6.0, 2.7.0, 3.0.0, or 3.1 are running with the web management interface accessible and read-only Administrator accounts configured.
