VulnerabilityCVE-2025-4404

A privilege escalation from host to domain vulnerability was found in the FreeIPA project.

A privilege escalation from host to domain vulnerability was found in the FreeIPA project. The FreeIPA package fails to validate the uniqueness of the krbCanonicalName for the admin account by default, allowing users to create services with the same canonical name as the REALM admin.

What happened

A privilege escalation from host to domain vulnerability was found in the FreeIPA project. The FreeIPA package fails to validate the uniqueness of the krbCanonicalName for the admin account by default, allowing users to create services with the same canonical name as the REALM admin.

When a successful attack happens, the user can retrieve a Kerberos ticket in the name of this service, containing the admin@REALM credential. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.

About this data

This record was ingested from a data source. Retrieved: Nov 4, 2026, 23:00 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
