The attacker uses scanners to locate web applications hosted on EC2 that are vulnerable to SSRF. They test various SSRF payloads by injecting the metadata endpoint into user-controllable parameters (e.g., url= , dest= , redirect= ). A probe might look like: https://victim.com/proxy?url=http://169.254.169.254/latest/meta-data/
To protect against this specific attack, implement the following security best practices Enforce IMDSv2: Transition from IMDSv1 to
The client must first issue a PUT request to generate a secret token.
