What potential vulnerability arises from an application’s failure to enforce appropriate input validation for data received via web forms?
Compromised two-factor authentication
Injection attacks
Ineffective SSL/TLS encryption
Increased network latency
The correct answer is 'Injection attacks', specifically SQL injection, which occurs when an attacker can successfully insert or manipulate SQL queries in the input fields of a web application, due to the application's failure to sanitize inputs. This can result in unauthorized viewing of data, data manipulation, or administrative operations on the database. The incorrect answers are meant to be distractors – SSL/TLS handles encryption of data; caching strategies might enhance performance; and input sanitization has no direct correlation with two-factor authentication implementation.
