CyberRota Analysis
AI-GeneratedA server-side request forgery vulnerability in Amazon AWS Systems Manager Agent prior to version 3.3.4851.0 allows authenticated remote users to bypass the denylist for remote destinations, potentially exposing link-local endpoints. This could lead to unauthorized access to temporary IAM role credentials, enabling attackers to act with elevated permissions from outside the managed instance. Organizations using affected versions of SSM Agent should prioritize upgrading to the latest version to mitigate this critical risk.

Original NVD Description
A server-side request forgery issue due to improper validation of equivalent address representations in the port forwarding to remote hosts functionality in Amazon AWS Systems Manager Agent (SSM Agent) before 3.3.4851.0 on all platforms might allow an authenticated remote user to bypass the remote destination denylist and reach link-local endpoints, potentially obtaining the temporary IAM role credentials of a managed instance and acting with that role's permissions from outside the instance, via a crafted destination host value that uses an alternate representation of a denied link-local address. To remediate this issue, users should upgrade to version 3.3.4851.0 or later.
