How to exploit Directory traversal vulnerability?

Backtrack has lots of tools for web-application testing. Directory traversal is one of the critical vulnerability in web-application. Previously i post about what is directory traversal & how to bypass its filter , but that process is manual, it can consume lots of time.But in bactrack automatic tools are available for this test which is DOTDOTPWN.

If you are on other distro , then you can download it form here.

It's a very flexible intelligent fuzzer to discover traversal directory vulnerabilities in software such as HTTP/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. It's the first Mexican tool included in BackTrack Linux .

Fuzzing modules supported in this version:

- HTTP

- HTTP URL

- FTP

- TFTP

- Payload (Protocol independent)

- STDOUT

./dotdotpwn.pl -m  http-url -S -u https://localhost/mutillidae/index.php?page=TRAVERSAL -k root -o unix   

In below figure; you can see vulnerable URL where directory traversal is applicable.
