DotDotPwn - The Directory Traversal Fuzzer.
It's a very flexible intelligent fuzzer to discover traversal directory vulnerabilities in software such as Web/FTP/TFTP servers, Web platforms such as CMSs, ERPs, Blogs, etc. Also, it has a protocol-independent module to send the desired payload to the host and port specified. On the other hand, it also could be used in a scripting way using the STDOUT module. It's written in perl programming language and can be run either under *NIX or Windows platforms.
