Weakness: CWE-1188

Description

A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.
