sssd 0.4.1 - Improper Authentication via Blank-Password Account Handling

Title source: llm
STIX 2.1

Description

The local_handler_callback function in server/responder/pam/pam_LOCAL_domain.c in sssd 0.4.1 does not properly handle blank-password accounts in the SSSD BE database, which allows context-dependent attackers to obtain access by sending the account's username, in conjunction with an arbitrary password, over an ssh connection.
