security about the IFS variable

[Loic]

I would like to know the problems related to the IFS variable.
Ok, I want to abuse it. I am in a wargame. There is a tool that
has user rights which are superior to me. They give me a hint.
I should use this prog which runs the unix command date.
Now I simply need to tell that program to execute a command
named pass, to get the password for the next level.The users of 
the level above told me it has something to do with the IFS variable.
I would appreciate any help.
