  Headline:         Persistent XSS in OpenStack Havana UI for Network Name
  Platforms:        OpenStack Horizon
  Versions:         Havana
  CVSS Score:       9.0
  CVSS Vector:      AV:N/AC:L/Au:S/C:C/I:C/A:C/E:POC/RL:U/RC:C
  CWE Tags:

  The Openstack Horizon user interface is vulnerable to XSS.  The Network Name
  parameter is not properly sanitized to prevent javascript injection, leading
  to persistent XSS.

  Steps to reproduce:

  1) Create a new network.  Use:

      <script>alert(1);</script>

  for the network name.  Disable both Subnet -> Create Subnet and Subnet Detail ->
  Enable DHCP.  Choose Create.

  2) Select Instances -> Launch Instance.  Receive alert.

  Recommendations:

  - Sanitize the rendering of "Network Name" string to prevent XSS.

  - Consider utilizing Content Security Policy (CSP). This can be used to prevent
  inline javascript from executing & only load Javascript files from approved
  domains.  This would prevent XSS, even in scenarios where user input is not
  properly sanitized.
