# This attack abuses a misconfigured proxy that allows access to the metadata
|
|
# IP or a name which resolves to the IP. A standard proxy request is made to
|
|
# the proxy using the full metadata URL, which the proxy will fulfull to its
|
|
# own metadata sevice.
|
|
#
|
|
# The proxy may also be vulnerable to host/port enumeration on localhost or
|
|
# inside the private network.

name: Openstack Metadata Service Check
|
|
author: sullo
|
|
severity: critical
|
|
description: The Openstack host is configured as a proxy which allows access to the instance metadata service. This could allow significant access to the host/infrastructure.
|
|
remediation: Disable the proxy or restrict configuraiton to only allow access to approved hosts/ports. Upgrade to IMDSv2 if possible.
