Static taint analysis method for intent injection vulnerability in android applications

Abstract

In the component communication of Android application, the risk that Intent can be constructed by attackers may result in malicious component injection. To solve this problem, we develop IntentSoot, a prototype for detecting Intent injection vulnerability in both public components and private components for Android applications based on static taint analysis. It first builds call graph and control flow graph of Android application, and then tracks the taint propagation within a component, between components and during the reflection call to detect the potential Intent injection vulnerability. Experimental results validate the effectiveness of IntentSoot in various kinds of applications.
