CVE-2016-9575 — Freeipa Freeipa security vulnerability

Medium CVSS 6.5

Ipa versions 4.2.x, 4.3.x before 4.3.3 and 4.4.x before 4.4.3 did not properly check the user's permissions while modifying certificate profiles in IdM's certprofile-mod command. An authenticated, unprivileged attacker could use this flaw to modify profiles to issue certificates with arbitrary naming or key usage information and subsequently use such certificates for other 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.
