Hi

am doing some security audit for a customer, and i come across a web
application that accept a GET request with a parameter that I believe is
a filename on the filesystem of the web server.

I am trying to get the application to display any files on the
filesystem. I have ried appending %00 etc.. but to no avail.

Anyone knows of more techniques to try?

How can one determine whether a web application is opening files for
read, hence making it possible for directory traversal attack?
