: This is the URL-encoded version of ../ , which means "go up one directory" in a file system. By repeating this, an attacker "climbs" out of the restricted web folder all the way to the server's root.

If an application is vulnerable to path traversal, an attacker could read this file, obtaining the aws_access_key_id and aws_secret_access_key of the root user or the user running the application, leading to full account compromise.

: The web server process (e.g., www-data , nginx , or apache ) should never run as the root user. If the web server runs as a low-privileged user, it will be blocked by the operating system from reading the /root/ directory, completely neutralizing this payload. : This is the URL-encoded version of

A web server should never run with root privileges. If the web server runs under a restricted user account (e.g., www-data ), an attacker utilizing directory traversal will be blocked from accessing the /root/ directory entirely. 3. Migrate to AWS IAM Roles (Eliminate Permanent Keys)

If an attacker successfully triggers the path traversal vulnerability and the web application runs with elevated privileges (such as root or via improper sudo permissions), the application will read this file and display its plain-text contents back to the attacker's browser or API client. Severe Implications of Credential Disclosure

: Repeating the step-back sequence ensures that the traversal escapes the restricted web server directory (e.g., /var/www/html/ ) and reaches the absolute root system directory ( / ). Most operating systems stop executing parent directory commands once they hit the root, making excessive repetitions highly effective.
