Technical description

Maxthon Browser for Android before 7.5.8.103 contains an address bar spoofing vulnerability that allows remote attackers to misrepresent a page's origin by exploiting the lack of a persistent fullscreen notification or trusted origin indicator when the Fullscreen API is invoked. Attackers can craft a malicious web page that renders a counterfeit address bar showing a trusted domain while displaying attacker-controlled content, tricking users who perform a single tap to enter fullscreen into disclosing credentials via phishing.
