High CVSS 9

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Software could allow an authenticated, remote attacker to make unauthorized changes to the system configuration. The vulnerability is due to insufficient authorization enforcement. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. A successful exploit could allow a user with read-only privileges to change critical system configurations using administrator privileges.

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.
