CVE-2025-4404
A privilege escalation from host to domain vulnerability was found in the FreeIPA project.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.97%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
