When combined, this payload attempts to trick a web application into reading the (which contains aws_access_key_id and aws_secret_access_key ) and sending the contents back to the attacker via a "callback" mechanism. How the Attack Works
The AWS credentials file , which contains plain-text Access Keys and Secret Access Keys .

To understand the mechanics of this security flaw, the raw input must first be decoded into its standard file system representation:
If a system is vulnerable to exploitation via a payload like this, the implications are severe: callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials
Callback URLs are ubiquitous in OAuth flows, webhooks, API integrations, and server-to-server notifications. For example, when a user authenticates with a third-party identity provider (IdP), the IdP sends a redirect (callback) to a pre-registered URL on the application’s domain. Similarly, webhooks call back to a user-specified endpoint to deliver events.
