In a typical SSRF attack, a hacker exploits a vulnerable web application that accepts a URL as input to fetch data from an external source. By substituting an external URL with a "file://" URI scheme, the attacker shifts the request's focus from the public internet to the server’s internal file system.
With these credentials, the attacker can run AWS CLI commands from their own machine: The Decoded Target : file:///root/
