:The payload targets the /home/ directory, where user-specific files are stored on Linux systems.
A Path Traversal attack occurs when an application uses user-controllable input to construct a pathname for a file or directory. By using special character sequences like ../ (dot-dot-slash), an attacker can "escape" the intended web root directory and access files elsewhere on the server's filesystem. In this specific payload: -file-..-2F..-2F..-2F..-2Fhome-2F-2A-2F.aws-2Fcredentials
The payload uses directory traversal sequences ( ../ or encoded as ..-2F ) to "break out" of the intended application directory and access the root filesystem. The goal is to reach the .aws/credentials file, which contains plain-text aws_access_key_id and aws_secret_access_key tokens.

Payload Mechanism : In this specific payload: The payload uses directory
# Sanitize user input import os def sanitize_path(user_input): # Reject path traversal sequences if '..' in user_input or user_input.startswith('/'): raise ValueError("Invalid path") return os.path.basename(user_input) Target File : /home/[user]/
