The payload php://filter/read=convert.base64-encode/resource=/root/.aws/credentials exploits Local File Inclusion (LFI) to bypass PHP filters and read sensitive AWS credentials, typically located outside the web root [1]. This attack succeeds due to improper user input validation, allowing attackers to access and base64-encode the credentials file for exfiltration [1].

First, you need to encode your AWS credentials (Access Key ID and Secret Access Key) using base64. This can be done using an online base64 encoding tool or programmatically.

If an attacker attempts to read a raw configuration file using a standard path like include('/root/.aws/credentials'); , two things usually happen:

The .aws/credentials file is a configuration file used by AWS CLI to store access keys and other credentials. This file typically resides in the user's home directory, e.g., ~/.aws/credentials . The file contains sensitive information, including: This can be done using an online base64

php://filter/read=convert.base64-encode/resource=/root/.aws/credentials Component Breakdown By converting it to Base64

If an attacker simply tried to include the raw credentials file, the server might throw an error or the data might get mangled. By converting it to Base64, the attacker gets a clean, alphanumeric string that bypasses simple security "firewalls" looking for keywords like [default] or aws_secret_access_key . Once the attacker sees the Base64 string on their screen, they simply decode it locally to regain the original text. The Impact: From LFI to Cloud Takeover
