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.

Red Hat Identity Management (IdM) has two important security vulnerabilities affecting its freeipa component. The first (CVE-2024-2698) allows a proxy service to impersonate any user to access other target services due to delegation rule flaws. The second (CVE-2024-3183) enables a user to obtain password hashes of all domain users and attempt offline brute force attacks. These vulnerabilities impact Red Hat Enterprise Linux 9.2 Extended Update Support and related variants. A security update addressing these issues is available from Red Hat.

A flaw was found in FreeIPA. This issue may allow a remote attacker to craft a HTTP request with parameters that can be interpreted as command arguments to kinit on the FreeIPA server, which can lead to a denial of service.
