Summary
Finit bundled getty can bypass /bin/login
Details

Finit is a fast init for Linux systems. Versions starting from 3.0-rc1 and prior to version 4.11 bundle an implementation of getty for the tty configuration directive that can bypass /bin/login, i.e., a user can log in as any user without authentication. This issue has been patched in version 4.11.
