Vulnerable Application

This module uses an existing session on an AWS EC2 instance to gather the metadata about the instance. As such, any EC2 instance with curl is an applicable target.

Verification Steps

  1. Get session
  2. Do use post/multi/gather/aws_ec2_instance_metadata
  3. Do set SESSION <session id>
  4. Do run
  5. See loot.

Options

Set VERBOSE to true if you would like the AWS EC2 instance metadata to be shown in addition to being stored.

Scenarios

Default, non-verbose mode:

resource (msf.rc)> use exploit/multi/ssh/sshexec
resource (msf.rc)> set PASSWORD test

RHOST => 192.168.2.2
resource (msf.rc)> run -j
[*] Exploit running as background job.
