Description:
Dennis Felsch and Mario Heiderich from the Horst Görtz Institute for
IT-Security, Ruhr-University Bochum reported a persistent XSS in Horizon. A
malicious administrator may conduct a persistent XSS attack by registering
a malicious host aggregate in Horizon Host Aggregate interface. Once
executed in a legitimate context this attack may reveal another admin
token, potentially resulting in a lateral privilege escalation. All Horizon
setups are affected.
