Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
