HtmlUnit vulenerable to arbitrary code execution
|
|
HtmlUnit is a Java-based library which provides web browser functionality to Java programs, and it supports JavaScript evaluation with embedded Mozilla Rhino engine.
Mozilla Rhino engine offers a feature to make Java objects available from JavaScript.
HtmlUnit initializes Rhino engine improperly, hence a malicious JavScript code can execute arbitrary Java code on the application(CWE-284).
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.
ICHIHARA Ryohei of DMM.com LLC reported this vulnerability to IPA.
JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
