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 Secure Firewall Management Center (FMC) Software, formerly Firepower Management Center Software, could allow an authenticated, remote attacker to elevate privileges on an affected device. To exploit this vulnerability, an attacker must have a valid account on the device that is configured with a custom read-only role. This vulnerability is due to insufficient validation of role permissions in part of the web-based management interface. An attacker could exploit this vulnerability by performing a write operation on the affected part of the web-based management interface. A successful exploit could allow the attacker to modify certain parts of the configuration.

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 a privilege escalation vulnerability in Cisco Secure Firewall Management Center (FMC). An authenticated attacker with a custom read-only role can bypass role restrictions in the web-based management interface due to insufficient validation of role permissions, allowing write operations that should be denied and modification of certain device configurations.

MitigationApply the Cisco patch/softwar update for FMC when available. Until then, limit custom read-only role assignments and monitor for unauthorized configuration changes.

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 FMC software version
    Log into the FMC web interface and navigate to System > About, or run 'show version' via CLI to confirm the installed FMC version
    Affected if The installed version matches 7.2.0, 7.2.0.1, 7.2.1, 7.2.2, 7.2.3, 7.2.3.1, 7.2.4, 7.2.4.1, 7.2.5, 7.2.5.1, 7.2.5.2, or 7.2.6
  2. Review custom user roles
    In the FMC web interface, go to System > Users > Roles to list all custom roles defined in the system
    Affected if Any custom roles with read-only permissions are defined in the system
  3. Check for role assignments to users
    Navigate to System > Users > Users and examine which users are assigned to custom read-only roles
    Affected if Any authenticated users are assigned custom read-only roles
  4. Audit recent configuration changes
    Review the FMC audit logs (System > Audit Log) and look for write operations or device configuration modifications performed by users with read-only roles
    Affected if Configuration changes were made by users assigned read-only or custom read-only roles
  5. Inspect role permission settings
    Examine the specific permissions granted to custom roles in System > Users > Roles, focusing on whether write operations are explicitly denied for device configurations
    Affected if Custom read-only roles exist but may allow write operations on certain device configurations

You are affected if your FMC runs version 7.2.0 through 7.2.6 and you have users assigned to custom read-only roles that may have performed unauthorized configuration changes.
