What is Directory Traversal?

Directory traversal Directory traversal, also known as path traversal. It   is a type of security vulnerability that occurs when an attacker manipulates input to access files or directories that are outside the intended scope of the application. This vulnerability exploits improper validation or sanitization of user-supplied file paths. How Directory Traversal Works When an application allows users to specify file names or paths (e.g., to upload, download, or view files), an attacker can manipulate the input to traverse the directory structure of the server.

For example: A vulnerable application has a URL parameter like this: https: //example.com/view?file=notes.txt An attacker could modify the input to something like: https://example.com/view?file=../../etc/passwd This could give access to sensitive files like /etc/passwd on a Unix-based system.
