sudobless

Let root grant a passwordless sudo session to a non-root shell. The user of the target shell must be in sudoers.

Usage

sudobless <pid of shell>

Example

User terminal	Root terminal
User fails to sudo and checks the shell pid: user@host:~$ sudo -i [sudo] password for user: ^C user@host:~$ echo $$ 96683 user@host:~$
	Root blesses user with the shell pid: root@host:~# sudobless 96683 root@host:~#
User can now sudo without a password prompt: user@host:~$ sudo -i root@host:~#

Install

Python 3 required

install -T -m744 -o root -g root sudobless.py /usr/local/bin/sudobless

Notes

• Use at your own risk. If you mess something up, run sudo -K as the user you blessed to wipe all the sudo sessions.
• This is tested on Arch Linux (kernel 5.5) x86_64 with sudo >= 1.8.22. It might not run on non-Linux
• The python is draft quality but it should be easy to read / audit
