: This targets the default location of the AWS CLI configuration file for the root user, which contains aws_access_key_id aws_secret_access_key Technical Impact If successful, an attacker can: Extract AWS Keys : Gain the Access Key ID and Secret Access Key. Escalate Privileges : Use the keys to perform actions via the AWS CLI or SDK. Data Breach
. Exposure of these credentials can lead to a full takeover of the victim's AWS infrastructure. Payload Breakdown -template-
: If the credentials belong to an administrative user, the attacker gains full control over the AWS account, including the ability to delete backups, steal data, or launch expensive resources.
: If this string is part of an exploit or a misconfigured system, it could imply an attempt to access or manipulate sensitive AWS credentials. The use of .. to traverse directories can be an attempt to find and access files outside of a restricted environment, potentially leading to security vulnerabilities. -template-..-2F..-2F..-2F..-2Froot-2F.aws-2Fcredentials
: Deploy a WAF to detect and block common directory traversal patterns (like ..%2F or ..-2F ) before they reach your application.
The core mechanism of a directory traversal attack relies on the relative path sequence ../ (dot-dot-slash).
If the backend code simply appends that string to a base path (e.g., /var/www/html/templates/ ), the operating system resolves the ../ commands, bypasses the template folder, and serves the contents of the AWS credentials file directly to the attacker’s browser. The Impact: Cloud Resource Hijacking : This targets the default location of the
The path -template-..-2F..-2F..-2F..-2Froot-2F.aws-2Fcredentials seems to reference a template or a specific directory/file structure related to storing AWS credentials. Let's decode it:
import os base_dir = '/var/www/templates' requested = os.path.abspath(os.path.join(base_dir, filename)) if not requested.startswith(base_dir): return "Invalid path", 403 with open(requested, 'r') as f: return f.read()
By chaining ..-2F..-2F..-2F..-2F together, the attacker attempts to climb four levels up the directory tree, escaping the standard public web directory (e.g., /var/www/html/ ) and reaching the absolute root directory ( / ) of the server. 3. root-2F.aws-2Fcredentials Exposure of these credentials can lead to a
When developers, system administrators, or applications interact with AWS services via the AWS Command Line Interface (CLI) or AWS SDKs, the system stores authentication configuration locally. On Linux and Unix-like operating systems, these are stored in the home directory of the user running the process.
: This frequently acts as a prefix targeting specific templating engines, application routes, or file-loading parameters known to be vulnerable to file inclusion.
If an attacker successfully retrieves this file via an LFI vulnerability, they gain immediate programmatic access to the organization's AWS infrastructure. Depending on the permissions attached to those credentials, the attacker could: Exfiltrate sensitive databases and intellectual property.
