File Inclusion Vulnerability (FIV) is a significant security flaw that affects web applications by allowing attackers to include files—either local or remote—that can execute malicious code or disclose sensitive information. This vulnerability often arises in applications that dynamically include files based on user input without proper validation or sanitization. FIV is classified primarily into two types: Local File Inclusion (LFI) and Remote File Inclusion (RFI). LFI occurs when an attacker exploits the inclusion of files present on the server, whereas RFI involves including files hosted on external servers. Both forms pose serious security risks, but RFI is particularly dangerous since it enables malicious actors to execute malicious code from third-party servers, leading to potential server compromise.

The danger of File Inclusion Vulnerabilities lies in their ability to facilitate unauthorized access, code execution, data theft, and even full system compromise. An attacker exploiting FIV can manipulate a web application to run malicious scripts, leading to data breaches, defacement, or server control. For example, if a web application fails to validate or sanitize user input that specifies which file to include, an attacker may provide a crafted URL to include malicious files. This type of vulnerability is particularly prevalent in web scripting languages that facilitate dynamic content, such as PHP, Perl, and ASP.NET.

Preventing FIV requires multiple security measures. First, developers should avoid including files based solely on user input; instead, they should validate and sanitize inputs rigorously. Employing whitelists, where only specific, predetermined files can be included, significantly reduces risk. Using secure coding practices, such as disabling the 'allow_url_include' directive in PHP configurations, also minimizes RFI risk. Additionally, employing framework-specific security features and regularly updating software to patch known vulnerabilities are essential. Web application firewalls (WAFs) can also detect and block malicious inclusion attempts, adding an additional layer of defense.

Languages vulnerable to file inclusion attacks are primarily web-based scripting languages such as PHP, ASP.NET, and Perl, which facilitate dynamic file processing and inclusion functions. For instance, PHP is particularly prone due to its functions like include(), require(), include_once(), and require_once(), which are susceptible if not properly managed. A study by Kurniawan (2015) highlighted that "PHP applications tend to be vulnerable because of improper input validation and lack of security best practices" (p. 112).

In conclusion, File Inclusion Vulnerability remains a paramount security concern in web development, especially in applications that dynamically load files based on user requests. Its potential to lead to unauthorized access and system compromise makes it critical for developers to implement robust input validation, systematic code reviews, and security best practices. As web applications continue to evolve, understanding and mitigating FIV will remain an essential aspect of cybersecurity efforts, safeguarding both data and infrastructure from malicious threats.
