Open Stack

Sorry I'm playing catch up a bit here but UUID collision definitely
should be infeasible.  Also image creation for non-admin users should be
subject to quotas, correct?

  Dear Openstack,

  The following information pertains to information discovered by
  Fortinet's FortiGuard Labs. It has been determined that a
  vulnerability exists in Openstack Glance module.  To streamline the
  disclosure process, we have created a preliminary advisory which you
  can find below. This upcoming advisory is purely intended as a
  reference, and does not contain sensitive information such as proof of
  concept code.

  As a mature corporation involved in security research, we strive to
  responsibly disclose vulnerability information. We will not post an
  advisory until we determine it is appropriate to do so in co-
  ordination with the vendor unless a resolution cannot be reached. We
  will not disclose full proof of concept, only details relevant to the
  advisory.

  We look forward to working closely with you to resolve this issue, and
  kindly ask for your co-operation during this time. Please let us know
  if you have any further questions, and we will promptly respond to

  Type of Vulnerability & Repercussions:

    # apt-get install software-properties-common
    # add-apt-repository cloud-archive:liberty

  Upcoming Advisory Reference:

    This vulnerability was discovered by Fortinet's FortiGuard Labs.

  Proof of Concept/How to Reproduce:
    1. Run script "sh curl_get_token_demo_work.txt" to get a valid non-admin or admin user token. Need to replace "tenantName", "username", "password" with your Openstack credential.
    2. Open script glance_DoS.py, and replace the line 30 "x-auth-token" value with the above token value, also replace the IP in url "http://10.0.0.11:9191/images" with your Openstack control node IP address.
    3. Run script glance_DoS.py which will keep running forever. You can check the images added by the script using console command "glance image-list" or clicking Dashboard images column. You will notice you cannnot delete the images added by the script. It prompts failure. Refer to the screenshots glance_cli_delete_fail.png and dashboard_delete_garbage_image_fail.png.
    4. Because either non-admin or admin user cannot delete the garbage images, with the above PoC running forever, more and more garbage images are added. So finally DoS can be caused because resource is exhausted or glance database query is very very slow.

   Notes:
       1) Run the PoC glance_DoS.py in Windows 7.
