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 input protection mechanisms of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to view data without proper authorization. This vulnerability exists because of a protection mechanism that relies on the existence or values of a specific input. An attacker could exploit this vulnerability by modifying this input to bypass the protection mechanism and sending a crafted request to an affected device. A successful exploit could allow the attacker to view data beyond the scope of their authorization.

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 · moderate confidence

This is an Insecure Direct Object Reference (IDOR) vulnerability in Cisco Firepower Management Center where the application relies on the existence or values of specific input parameters for authorization checks. An authenticated attacker can manipulate these input values to bypass protection mechanisms and access data outside their authorized scope.

MitigationApply the vendor patch from Cisco for FMC Software. The fix requires implementing proper authorization validation regardless of input parameter presence or values.

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. Confirm the installed product is Cisco Firepower Management Center
    Identify the product by logging into the web interface or running 'show version' on the device CLI. Look for 'Firepower Management Center' or 'Secure Firewall Management Center' in the product name.
    Affected if The product is Cisco Firepower Management Center or Cisco Secure Firewall Management Center
  2. Determine the installed software version
    In the FMC web interface, go to System > Updates or use the CLI command 'show version' to obtain the exact version number.
    Affected if The version is any release prior to 7.1.0 (for example, 7.0.x, 6.x, or earlier)
  3. Verify the web interface is accessible to authenticated users
    Confirm the FMC web interface (typically HTTPS on port 443) is reachable and that user accounts exist with access to the application.
    Affected if The FMC web interface is exposed and accepts authenticated sessions, allowing an attacker to manipulate request parameters

A user is affected if they are running Cisco Firepower Management Center or Secure Firewall Management Center with a version lower than 7.1.0 and the web interface is accessible to authenticated users.

Upgrade available Upgrade to 7.1.0 or later
Fixed in 7.1.0
Interim mitigation

Apply the vendor patch from Cisco for FMC Software. The fix requires implementing proper authorization validation regardless of input parameter presence or values.

Recommended fix Moderate confidence

Secure Firewall Management Center 7.1.0 or later

  1. 1. Back up the current FMC configuration and ensure you have a recovery plan in case of upgrade failure
  2. 2. Verify current FMC version by navigating to System > About > System Information in the FMC web interface
  3. 3. Download Cisco Secure Firewall Management Center version 7.1.0 or later from the Cisco Software Download page (requires valid Cisco service contract)
  4. 4. Upload the upgrade package to the FMC via the web interface: go to System > Updates > Product Updates
  5. 5. Schedule the upgrade during a maintenance window as the FMC will be temporarily unavailable
  6. 6. Initiate the upgrade and monitor progress; do not interrupt power or network to the device
  7. 7. After reboot, verify the upgrade was successful by checking the version at System > About > System Information
  8. 8. Test that the vulnerability is remediated by verifying proper authorization boundaries are enforced
Caveat Major version upgrades may introduce changes to functionality, API behavior, or configuration compatibility; review Cisco FMC 7.1.0 release notes for any breaking changes before upgrading
