CVE-2018-0278 — Cisco Secure Firewall Management Center security vulnerability

Medium CVSS 6.5

A vulnerability in the management console of Cisco Firepower System Software could allow an unauthenticated, remote attacker to access sensitive data about the system. The vulnerability is due to improper cross-origin domain protections for the WebSocket protocol. An attacker could exploit this vulnerability by convincing a user to visit a malicious website designed to send requests to the affected application while the user is logged into the application with an active session cookie. A successful exploit could allow the attacker to retrieve policy or configuration information from the affected software and to perform another attack against the management console. Cisco Bug IDs: CSCvh68311.

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.
