Ipa: freeipa: freeipa: unauthenticated ldap client can obtain administrator credentials via the self-managed-token aci

A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.
