Overview

Affected versions of this package are vulnerable to Arbitrary Code Execution by allowing an attacker to create special subclasses of InvocationTargetException that escape the exception sanitization. This is because JUnit extracts the cause in a trusted context before the exception reaches Ares. This means that arbitrary student code can be executed in a trusted context, and that in turn allows disabling Ares and having full control over the system.
