Input Validation Attacks

Input validation attacks are a method of cyberattack in which the attacker injects malicious input that can be interpreted and executed by a target system to exploit its vulnerabilities. Input validation attacks can employ a variety of input types such as code, scripting, and commands. The most common input validation attack types are buffer overflow attacks, canonicalization attacks, cross-site scripting (XSS) attacks, and SQL injection (SQLi) attacks.
