OSSA-2015-009: Persistent XSS in Horizon metadata dashboard¶
May 25, 2015
Horizon: 2014.2 versions through 2014.2.3 and version 2015.1.0
Sunil Yadav from IBM Security Services reported a persistent XSS in Horizon. An authenticated user may conduct a persistent XSS attack by setting a malicious metadata to a Glance image, a Nova flavor or a Host Aggregate and tricking an administrator to load the update metadata page. Once executed in a legitimate context this attack may result in a privilege escalation. All Horizon setups are affected.
