Describe the type of attack that is related to poor input validation.

In the following scenario, what should the input validation parameters be? A class registration web form requires that students enter their current year. The entry options are numbers from 1 to 4 that represent the following: freshmen=1, sophomores=2, juniors=3, and seniors=4.

Solution

The attacks which are related to poor data validation are:file system attacks, data invalidity attacks, XSS attacks. These attacks are resulted when malicious data gets injected from users through a unchecked form. This attack can destroy the server\'s metadata and cause ambiguities in the already existing records.

Input validation parameters in the given example: HTTP verb tampering test which will check for the number (1,2,3 or 4) in the request. If there is any other number apart from these 4, then it is an invalid data.
