LINE client for Android versions prior to 14.20 contains a UI spoofing vulnerability in the in-app browser where the full-screen security Toast notification is not properly re-displayed when users return from another application, potentially allowing attackers to conduct phishing attacks by impersonating legitimate interfaces.
Weakness
The user interface (UI) does not properly represent critical information to the user, allowing the information - or its source - to be obscured or spoofed. This is often a component in phishing attacks.

Extended Description
If an attacker can cause the UI to display erroneous data, or to otherwise convince the user to display information that appears to come from a trusted source, then the attacker could trick the user into performing the wrong action. This is often a component in phishing attacks, but other kinds of problems exist. For example, if the UI is used to monitor the security state of a system or network, then omitting or obscuring an important indicator could prevent the user from detecting and reacting to a security-critical event. UI misrepresentation can take many forms:
