LFI - 10 things to know with detail

• LFI stands for Local File Inclusion, which is a type of vulnerability that allows an attacker to include files on a server through the web browser.
• LFI can be exploited by manipulating input parameters that are used to include files in a web application, such as file paths or URLs.
• In some cases, LFI can lead to Remote Code Execution (RCE), allowing an attacker to execute arbitrary code on the server.
• LFI attacks can be used to access sensitive files on the server, such as configuration files, user data, or even system files.
• LFI vulnerabilities are typically found in web applications that use dynamic file inclusion methods, such as PHP's include() or require() functions.
• To prevent LFI attacks, developers should validate and sanitize input parameters that are used to include files, and avoid using user-controlled input in file paths.
• Security tools like web application firewalls (WAFs) can help detect and prevent LFI attacks by monitoring and filtering incoming requests.
• LFI attacks can be detected by looking for suspicious file inclusion patterns in web server logs, such as requests for system files or unexpected file paths.
• Penetration testers and security researchers often use LFI vulnerabilities to demonstrate the impact of insecure file inclusion in web applications.
• It is important for developers to regularly scan and test their web applications for LFI vulnerabilities, as they can pose a significant risk to the security of the application and the server.
