LFI (Local File Inclusion), RFI (Remote File Inclusion), and XSS (Cross-Site Scripting) are web security vulnerabilities.
LFI (Local File Inclusion): This occurs when a web application includes files on the server without proper validation. An attacker may exploit this vulnerability to include sensitive files, potentially leading to unauthorized access or information disclosure.
RFI (Remote File Inclusion): Similar to LFI, RFI involves including files, but in this case, the attacker can include files from a remote server. If the application doesn't validate inputs properly, an attacker might include malicious files, allowing them to execute arbitrary code on the server.
XSS (Cross-Site Scripting): XSS happens when an attacker injects malicious scripts into web pages viewed by other users. This can lead to the theft of sensitive information, session hijacking, or defacement of websites. XSS can be stored in the server (persistent), reflected from the user's input (non-persistent), or executed in a way that combines both.
