What are some examples of input sanitization failures?

Input sanitization failures occur when software does not properly validate or clean user input, leading to vulnerabilities. For example, SQL injection attacks happen when an attacker inputs malicious SQL code into a form field, which the application then executes.

Can you give me a specific case of a SQL injection failure?

Sure! One famous case is the 2008 Heartland Payment Systems breach, where attackers exploited a SQL injection vulnerability to access over 130 million credit card numbers.

What are some other types of input sanitization failures?

Other types include Cross-Site Scripting (XSS), where attackers inject malicious scripts into web pages, and Command Injection, where they execute arbitrary commands on the server.

How can developers prevent these failures?

Developers can prevent these failures by using prepared statements, validating input data, and employing security libraries that automatically sanitize inputs.
