Attack Technique

Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.

Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
