Rule Vulnerability

Local File Inclusion

Local File Inclusion (LFI) attackers attempt to trick the web server into executing a file local to its own file system. The attacker might have saved the file there in another way first, or the target file could be a local executable that should not be accessible to the web server otherwise. A successful LFI can lead to data leaks or remote code execution. Avoid dynamic inclusion of user input files, or whitelist files that may be included.
