If successful, this attack results in a . An attacker who obtains these credentials can:
Avoid storing permanent, plain-text AWS credentials on servers. If your application runs on AWS EC2, use . If it runs on Kubernetes, use IRSA (IAM Roles for Service Accounts) . These systems use temporary, automatically rotating tokens instead of static credentials files. 4. Deploy a Robust WAF
To understand the danger, we have to break the payload down into its functional parts: -file-..-2F..-2F..-2F..-2Fhome-2F-2A-2F.aws-2Fcredentials
The string you've shared looks like a Local File Inclusion (LFI) Path Traversal
The file /home/username/.aws/credentials contains plaintext secrets structured like this: If successful, this attack results in a
This indicates an attempt to invoke the local file system handler, bypassing standard web routing.
If an attacker sends a request to /view-file?file=../../../../home/ubuntu/.aws/credentials , the path.join function may resolve the path outside of the intended public directory, reading the sensitive file from the host operating system instead. Remediation and Mitigation Strategies If it runs on Kubernetes, use IRSA (IAM
The vulnerability is often found in endpoints that take a filename or path as a parameter, such as:
What or framework your application uses.
Use AWS Identity and Access Management (IAM) Roles instead of hardcoded access keys.
