How Symlink Attack Manifests in Aws

Symlink attacks in Aws applications typically exploit the file system's symbolic link functionality to access files and directories outside the intended scope. In Aws applications, this vulnerability often appears when user-controlled paths are passed directly to file operations without proper validation.

The most common manifestation occurs in file upload functionality. Consider an Aws application that processes file uploads and stores them in a user-specific directory. If the application constructs file paths using user input without proper sanitization, an attacker can craft a path containing ../ sequences to traverse directories and access sensitive files.
