What are some real-world examples of input validation failures?

Input validation failures occur when a system does not properly check the data it receives. A notable example is the 2017 Equifax data breach, where attackers exploited a vulnerability due to inadequate input validation, compromising sensitive information of millions.

Can you give me another example?

Sure! Another example is the SQL injection attack on the TalkTalk website in 2015. Hackers were able to access customer data because the website failed to validate user input properly, leading to a significant data breach.

What are the consequences of these failures?

The consequences can be severe, including data breaches, financial loss, legal repercussions, and damage to a company's reputation. In some cases, it can also lead to identity theft for affected individuals.

How can companies prevent input validation failures?

Companies can prevent these failures by implementing strict input validation rules, using prepared statements for database queries, and regularly testing their systems for vulnerabilities.
