Name of the Vulnerable Software and Affected Versions sssd version 0.4.1

Description The issue arises from the local handler callback function in server/responder/pam/pam LOCAL domain.c, which does not properly handle blank-password accounts in the SSSD BE database. This allows attackers to obtain access by sending the account's username, along with an arbitrary password, over an ssh connection.

Recommendations For sssd version 0.4.1, as a temporary workaround, consider disabling the local handler callback function until a patch is available. Restrict access to blank-password accounts in the SSSD BE database to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
