Описание
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.
Отчет
This vulnerability is marked as Important rather than a Moderate because it allows a local or authenticated attacker to escalate privileges from host-level to full domain-level administrative access within a FreeIPA-managed environment. By exploiting the lack of uniqueness enforcement on the krbCanonicalName attribute, an attacker can craft a principal with the same canonical name as the domain admin, for example, root@REALM, and obtain a Kerberos service ticket. This results in the impersonation of the admin identity, granting unrestricted access to sensitive systems and data. Since Kerberos-based authentication is trusted across the domain, this breach compromises the entire security boundary of the realm, allowing administrative tasks like user management, policy manipulation, and credential extraction.
Меры по смягчению последствий
There's no available mitigation other than updating to the package version.
