Standard attack pattern
Draft
CAPEC-503: WebView Exposure
An adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.

Overview
CAPEC-503 (WebView Exposure) is a standard-level attack pattern catalogued by MITRE in the Common Attack Pattern Enumeration and Classification (CAPEC). It describes a recurring method attackers use to exploit software weaknesses.
What the attacker needs
Prerequisites
- This type of an attack requires the adversary to convince the user to load the malicious web page inside the target application. Once loaded, the malicious web page will have the same permissions as the target application and will have access to all registered interfaces. Both the permission and the interface must be in place for the functionality to be exposed.
How to mitigate it
Defenses that reduce the risk of CAPEC-503.
- To mitigate this type of an attack, an application should limit permissions to only those required and should verify the origin of all web content it loads.
