GHSA-2M59-RW4G-9G7X

Vulnerability from github – Published: 2022-05-24 17:44 – Updated: 2022-05-24 17:44

Details

The Debian shadow package before 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.
