CVE-2024-20482 — Cisco Secure Firewall Management Center security vulnerability

Medium CVSS 6.5

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.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
