I have the script on one of my systems that I can't modify at all, but need to fix its behavior. I can only pass arguments to the script. I am looking if it is possible to do some trickery with the arguments to amend script's behavior.

You are seeking advice from us on how to write a bug exploit?

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
