| 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. |

Workarounds
CNA: Set ldap_sudo_search_base explicitly in /etc/sssd/sssd.conf to restrict the search to the designated sudoers container: [domain/example.com] ldap_sudo_search_base = ou=sudoers,dc=example,dc=com Additionally, restrict LDAP ACLs to prevent non-admin principals from creating sudoRole objects outside the designated sudoers container.
There are currently no legacy QID mappings associated with this CVE.
