Local File Inclusion (LFI)

Local File Inclusion (LFI) — Web Application Penetration Testing

Local File Inclusion (LFI) allows an attacker to include files on a server through the web browser. This vulnerability exists when a web application includes a file without correctly sanitising the input, allowing and attacker to manipulate the input and inject path traversal characters and include other files from the web server.
