CAPEC-503: WebView Exposure

Attack Pattern ID: 503
Abstraction: Standard
Status: Draft
Presentation Filter:
+ Description
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.
+ Relationships

The table(s) below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.

ChildOfMeta Attack PatternMeta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.122Privilege Abuse
+ 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.
+ Mitigations
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.
