CVE-2018-15405 — Cisco Ucs Director security vulnerability

Medium CVSS 6.5

A vulnerability in the web interface for specific feature sets of Cisco Integrated Management Controller (IMC) Supervisor and Cisco UCS Director could allow an authenticated, remote attacker to access sensitive information. The vulnerability is due to an authorization check that does not properly include the access level of the web interface user. An attacker who has valid application credentials could exploit this vulnerability by sending a crafted HTTP request to the web interface. A successful exploit could allow the attacker to view sensitive information that belongs to other users. The attacker could then use this information to conduct additional reconnaissance attacks.

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.
