How do I use command arguments with Cmnd_Alias in sudoers?
2 answers
I want to be able to run fdisk -l as any user, without getting the whole fdisk: cannot open /dev/sda: Permission denied message.
I don't see how fdisk -l can be used for malicious purposes.
I have a PHP script, which first checks if the user is logged into my website, and if they are admin.
Then I have an admin control panel, where it shows the output of fdisk -l, however, I am getting the error fdisk: cannot open /dev/sda: Permission denied.
There is no user input, so they can't inject arguments into the command.
permissions su fdisk

A solution would be to create a program calling fdisk. Writing it in CC++ would be easy, you just need a compiler. Then change the owner of the executable to root and give it the SUID right (giving the SUID to a script won't work that's why you'll need an executable not a script). Make sure no other user can write to that file or it could cause a security issue.
