![]() This looks as a perfect place to try for LFI. ![]() Since LFI occurs when paths passed to include statements are not properly sanitized, in a blackbox testing approach, we should look for scripts which take filenames as parameters. Although most examples point to vulnerable PHP scripts, we should keep in mind that it is also common in other technologies such as JSP, ASP and others. This vulnerability occurs, for example, when a page receives, as input, the path to the file that has to be included and this input is not properly sanitized, allowing directory traversal characters (such as dot-dot-slash) to be injected. Local file inclusion (also known as LFI) is the process of including files, that are already locally present on the server, through the exploiting of vulnerable inclusion procedures implemented in the application. Code execution on the client-side such as JavaScript which can lead to other attacks such as cross site scripting (XSS).This can lead to something as outputting the contents of the file, but depending on the severity, it can also lead to: The vulnerability occurs due to the use of user-supplied input without proper validation. The File Inclusion vulnerability allows an attacker to include a file, usually exploiting a “dynamic file inclusion” mechanisms implemented in the target application.
