Upgrade Debian:11 shadow to version 1:4.5-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream shadow package and not the shadow package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The Debian shadow package before 1:4.5-1 for Shadow incorrectly lists pts/0 and pts/1 as physical terminals in /etc/securetty. This allows local users to login as password-less users even if they are connected by non-physical means such as SSH (hence bypassing PAM's nullok_secure configuration). This notably affects environments such as virtual machines automatically generated with a default blank root password, allowing all local users to escalate privileges.
