# Maxthon Android browser: fullscreen mode lets pages fake the address bar

Maxthon Browser for Android before 7.5.8.103 does not show a persistent fullscreen notice or trusted-origin indicator when a page enters fullscreen. A malicious page can draw a fake address bar showing a trusted domain, so a user who taps once to go fullscreen may type credentials into an attacker's page.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Open Maxthon on Android and check the version under the app's About or settings screen; `7.5.8.103` or later is the fixed build named in the advisory.

## Fix

- Maxthon Browser for Android: `7.5.8.103`

## From the sources

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.
