Directory traversal (also known as path traversal) is an exploit targeting applications that accept user-supplied filenames or paths without proper sanitization. Path Traversal Mechanics
: These define a set of permissions for making AWS requests.
Relying entirely on string filters to stop directory traversal is an architectural anti-pattern. Robust defense-in-depth requires addressing both software vulnerabilities and cloud identity management.

Instead of baking access keys into configuration files, assign an IAM Role directly to the Amazon EC2 instance or ECS task definition. The application code will automatically retrieve temporary, self-rotating credentials via the AWS Instance Metadata Service (IMDS).
: The application reads the AWS credentials file from the server's disk and displays the contents back to the attacker in the HTTP response. The Ultimate Goal: AWS Credentials Exfiltration Directory traversal (also known as path traversal) is
: The application requests a file from the user, such as https://example.com .
user. The application should only have permissions to access its own directory. AWS Best Practices for EC2 instances instead of storing static credentials in .aws/credentials remediation guide for a specific programming language like : The application reads the AWS credentials file
: The AWS root user has total control over every resource in the account.
Attackers can sync S3 buckets, download databases, or delete infrastructure.
The compromise of AWS root or service credentials presents catastrophic risks to an enterprise. Once an external actor acquires valid access keys, they can execute actions authorized under that specific identity.
