For example, in sudo -l i discovery that I can run scp through sudo with Makulele user. I would like to know how to execute a bash command using scp. Example:

sudo -u makulele scp executeBASHcommandASmakulele 

Maybe using -S option or -p with suid flag as well... Does anyone have a way to do this?

  • You could use scp to copy a setuid binary and change the user, then you can execute the copied file to obtain the setuid privilege. – wireghoul Feb 7 '17 at 4:40

scp doesn't execute commands. I'm not entirely sure why you think it should.

Perhaps you want to run executeBASHcommandASmakulele on the local system as the makulele user:

sudo -u makulele executeBASHcommandASmakulele

Or if it's a script/program in the current directory,

sudo -u makulele ./executeBASHcommandASmakulele

Or perhaps you want to run executeBASHcommandASmakulele on a remote system as the makulele user:

sudo -u makulele ssh remote_host executeBASHcommandASmakulele
  • in that case the only option I had was to execute commands by scp – Guilhermek Jul 29 '18 at 12:47
  • You can't execute commands through scp. If that's what you think you were doing, you weren't. – roaima Jul 29 '18 at 13:51
  • In hack.me had a challenge that you need to scape from a chroot jail and one level of this jail was the 'scp' as the only disponible command. Whatever, I'm not doing hack.me challenges anymore. Thanks a lot for the reply. – Guilhermek Aug 6 '18 at 22:21
