The path mentioned in your fetch request (/root/.aws/config) suggests the file is owned by the root user. This raises a massive red flag: Do not run AWS CLI commands as the root user of your operating system unless absolutely necessary.

In a 2022 incident, a bug bounty hunter found a parameter shared_file in a staging server that accepted base64-encoded strings. One string decoded to file:///root/.aws/config. The server returned the config file, which referenced a [prod] profile. The attacker then changed the path to /root/.aws/credentials and exfiltrated valid root keys. fetch-url-file-3A-2F-2F-2Froot-2F.aws-2Fconfig

Within 6 hours, the attacker spun up 200 GPU instances for crypto mining, resulting in a $50,000 bill before detection. The root cause? An internal dashboard using file:// to read local templates without sanitization. The path mentioned in your fetch request ( /root/

Only attempt if you have proper authorization and legal access. From within a container where the file is accessible:

    Hard-coding long-lived Access Keys is a security risk. You can configure the config file to automatically assume an IAM role using temporary credentials.

    [profile admin-role]
    role_arn = arn:aws:iam::123456789012:role/AdminAccess
    source_profile = default
    mfa_serial = arn:aws:iam::123456789012:mfa/username
    

    In this setup, when you use --profile admin-role, the CLI will automatically grab temporary credentials from your default profile and assume the Admin role, optionally asking for your MFA code.
