Уязвимость централизованной системы по управлению идентификацией пользователей FreeIPA, связанная с неправильным контролем доступа, позволяющая нарушителю повысить свои привилегии до уровня администратора домена и оказать воздействие на конфиденциальность целостность и доступость защищаемой информации

Уязвимость сервера FreeIpa, связанная с недостатками разграничения доступа, позволяющая нарушителю повысить свои привилегии

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.

A privilege escalation flaw from host to domain administrator was found in FreeIPA. This vulnerability is similar to CVE-2025-4404, where it fails to validate the uniqueness of the krbCanonicalName. While the previously released version added validations for the admin@REALM credential, FreeIPA still does not validate the root@REALM canonical name, which can also be used as the realm administrator's name. This flaw allows an attacker to perform administrative tasks over the REALM, leading to access to sensitive data and sensitive data exfiltration.
