OpenStack Horizon did not properly process Heat templates.

Software Description

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.
