Summary
Details

HtmlUnit prior to 2.37.0 contains code execution vulnerabilities. HtmlUnit initializes Rhino engine improperly, hence a malicious JavScript code can execute arbitrary Java code on the application. Moreover, when embedded in Android application, Android-specific initialization of Rhino engine is done in an improper way, hence a malicious JavaScript code can execute arbitrary Java code on the application.
