Summary

Vulnerability reported (CVE-2025-4404). Successful exploitation can lead to full system takeover. Exploitable via krbCanonicalName.

Original description

The description as published by the source.

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.
