USN-2206-1: OpenStack Horizon vulnerability

6 May 2014

OpenStack Horizon did not properly process Heat templates.



  • horizon - Web interface for OpenStack cloud infrastructure


Cristian Fiorentino discovered that OpenStack Horizon did not properly
perform input sanitization for Heat templates. If a user were tricked into
using a specially crafted Heat template, an attacker could conduct
cross-site scripting attacks. With cross-site scripting vulnerabilities, if
a user were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents, or
steal confidential data, within the same domain.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.10

In general, a standard system update will make all the necessary changes.
