Source Code Exposure via File Inclusion

Source Code Disclosure - File Inclusion is a type of security vulnerability where an attacker can exploit improper handling of file paths or inputs by a web application to include and execute files from the server. This can lead to exposure of sensitive information, such as source code, configuration files, or other critical data. The vulnerability typically arises from insufficient validation of user inputs or insecure coding practices, allowing the attacker to manipulate the file path to include unauthorized files, potentially leading to further security breaches and exploitation.


Validate and sanitize user inputs, implement strict whitelisting for file types and paths, and avoid direct use of user-supplied input in file functions. Configure the server to restrict access to sensitive directories, use Web Application Firewalls (WAFs), and regularly update your software.
