Adversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other applications with Internet accessible open sockets, such as web servers and related services.

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.
