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 Firepower Management Center could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of the affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions on the targeted device via a web browser and with the privileges of the user. Cisco Bug IDs: CSCvb19750.

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 CSRF vulnerability exists in the Cisco Firepower Management Center web-based management interface due to insufficient anti-CSRF protections. An unauthenticated remote attacker can craft malicious links that, when clicked by an authenticated user, cause the user's browser to execute unauthorized actions with the user's privileges on the affected device.

MitigationApply the vendor patch from Cisco for CSCvb19750 to implement proper CSRF token validation in the web management interface.

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 product and version
    Access the Firepower Management Center web interface and check the System > Updates page, or log into the appliance CLI and run 'show version' or 'sudo sfcli -c show system-info' to display the firmware version.
    Affected if The version matches 6.0.1, 6.1.0, 6.2.0, 6.2.1, 6.2.2, or 6.2.3 for either the Management Center or the Firepower Appliance firmware.
  2. Confirm web management interface is accessible
    Verify that the Firepower web-based management interface is reachable on the network (typically ports 443 or 8443). Attempt to reach the login page via HTTPS.
    Affected if The web interface is exposed and reachable, making CSRF attacks possible against authenticated users.
  3. Inspect HTTP responses for CSRF token presence
    Log into the management interface using a test account, then use browser developer tools or a proxy (Burp Suite) to capture HTTP responses. Examine POST request bodies and response headers for anti-CSRF tokens such as 'csrf_token', 'CSRFToken', or similar parameters.
    Affected if No anti-CSRF tokens are found in the web interface requests, indicating the vulnerability is present.
  4. Verify session tokens change on re-authentication
    Log out and log back in, then compare the CSRF token values from the first and second sessions. They should be different.
    Affected if Tokens remain the same across sessions or are absent entirely, confirming insufficient CSRF protection.

If the installed version is 6.0.1 through 6.2.3 and the web management interface is accessible without proper CSRF token validation, the environment is affected by CVE-2018-0365.
