"The remote NewStart CGSL host, running version MAIN 5.04, has sssd packages installed that are affected by a
vulnerability:
- It was found that sssd's sysdb_search_user_by_upn_res()
function 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.
