Exploiting the Xamarin.Android DLL hijack vulnerability

via Securify – blog – Exploiting the Xamarin.Android DLL hijack vulnerability.

Last week a security advisory was posted to the Full-Disclosure mailing list concerning a vulnerability in Xamarin.Android. Xamarin.Android allows the creation of Android apps in C#. This vulnerability allows any Android app with write access to external storage to create a malicious DLL file that will be executed by an affected app. This issue is addressed in Xamarin 5.1; vulnerable apps need to be recompiled with Xamarin version 5.1 or newer in order to resolve this vulnerability.

This article explains how this issue can be exploited in order to execute arbitrary code. A vulnerable Android app needs to be found in order to test this issue. This is left as a reader’s exercise.
