It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.
CVSS 3 base score: 8.8
according with RHEL "Versions prior to sssd-1.12.0 are not affected (affected commit: 7ecb5ae)"
