How do attackers exploit web application vulnerabilities?

• A. By using secure coding practices
• B. By maliciously written code and poor validation
• C. By enhancing input and output controls
• D. By implementing stricter firewall rules

Answer: (B)

Attackers exploit web application vulnerabilities primarily through the use of maliciously written code and poor validation practices. When developers do not properly validate user inputs, attackers can inject harmful code into web applications. This can lead to various attacks such as SQL injection, cross-site scripting (XSS), and remote code execution, among others. By manipulating input fields that the application fails to sanitize, attackers may gain unauthorized access to data, manipulate web sessions, or even take control of the underlying server. In contrast, secure coding practices, enhancing input and output controls, and implementing stricter firewall rules are all defensive measures aimed at preventing such attacks. While these strategies strengthen the security posture of web applications, they do not represent how vulnerabilities are exploited. Secure coding ensures that code is resilient against attacks, while robust input/output controls help filter and sanitize any data processed by the application. Stricter firewall rules serve as a barrier against unauthorized access but do not directly address the exploitation of vulnerabilities within the application itself.
