SSSD stores its cached data in an LDAP like local database file using libldb. To lookup cached data LDAP search filters like ‘(objectClass=user) (name=user_name)’ are used. However, in sysdb_search_user_by_upn_res(), the input is not sanitized and allows to manipulate the search filter for cache lookups. This would allow a logged in user to discover the password hash of a different user (CVE-2017-12173).
