Lets look more closely at what RFI is, how it happens, and how we can make a vulnerable application bend to our will. LFI vulnerabilities allow an attacker to read (and sometimes execute) files on the victim machine. One of the most dangerous types of vulnerabilities we can find while penetration testing is Remote File Inclusion (RFI). Perhaps one of the biggest issues we see is people using $_GET or another unfiltered variable inside of an include, include_once, require or require_once statement which is a major security risk.
