Iframe phishing in HAX CMS before 11.0.0 allows remote attackers to harvest a visiting user's credentials through a crafted site. The website block accepts an arbitrary target URL and renders it in an iframe, causing a visitor's browser to contact an attacker-controlled server. Exploitation requires site-author access and a victim who visits the malicious site and enters credentials into the resulting sign-in prompt.
