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.

: 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.
