Summary
Documents how an AWS IAM condition that relies on
aws:UserAgentcan be bypassed by modifying the final outgoingUser-Agentfrom AWS CLI v2.HackTricks already documents changing the User-Agent from Boto3. This contribution extends the technique to the AWS CLI by using a legacy plugin and Botocore
before-sendhook to modify the fully prepared HTTP request immediately before transmission.The page explains why
aws:UserAgentis a client-controlled signal rather than a strong authorization boundary and documents the difference between changing the header during earlier request-building stages and atbefore-sendtime. Examples are generic and contain no lab-specific material.This contribution is for the ARTE certification extra-points requirement.
