Metabadger is a security tool designed to help organizations secure AWS EC2 instances against Server-Side Request Forgery (SSRF) attacks by managing the Instance Metadata Service (IMDS) configuration. The tool addresses security vulnerabilities associated with IMDSv1, which can be exploited through SSRF attacks to access instance credentials and session tokens. Attackers can leverage these credentials to pivot into AWS environments and escalate privileges beyond the compromised instance. Key functionalities include: - Diagnosing current IMDS usage across EC2 instances - Preparing instances for upgrade to the more secure IMDSv2 - Automating the transition from IMDSv1 to IMDSv2 - Disabling the Instance Metadata Service on instances where it is not required - Reducing attack surface by eliminating unnecessary metadata service exposure The tool helps organizations implement AWS security best practices by ensuring instances use IMDSv2, which provides additional security controls including session tokens and hop limits that make SSRF exploitation significantly more difficult. Metabadger supports compliance with AWS security recommendations for protecting against metadata service abuse and helps prevent the type of attacks that have been used in notable security breaches involving cloud infrastructure.
