Summary
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.
Exploit prediction
1.98% chance of exploitation in the next 30 days, higher than 80% of all scored CVEs (FIRST EPSS, 2026-11-08).
