The first thing that comes to mind is brute forcing. It is effective if you have some knowledge of the pattern of the file names. So if you know that the files are all references using something like /docs/tempXXXXX.pdf Where XXXXX is a random string, A simple Perl script would allow you to iterate through all options In many cases you will find that there is logic in the file names that makes brute forcing much faster. Another option is XSS. If you have some XSS vulnerability, than what you would want to steal from other users are these filenames. On a higher level, this problem is a lot like the more usual session management problem. The file name is sort of a "session identifier". If names are very long and very random it makes brute forcing difficult just as long and random session identifiers do. And just as session identifiers are prime target for XSS so are these file names.

I don't like it but the app owner wants me to demonstrate that someone could guess the URLs. I have tried a number of spider tools but they are based on links so they don't pull up anything. I am wondering if there is a tool or another method where I could find out all the URLs on the web site. The funny thing is I saw this same kind of system with the same explanation just the other week at
another
company. Maybe its a new trend... Regards, sakaba
