(BeanShell: Arbitrary code execution)

    An application that includes BeanShell on the classpath may be
      vulnerable if another part of the application uses Java serialization or
      XStream to deserialize data from an untrusted source.
  
Impact :

    Remote attackers could execute arbitrary code including shell commands.
  
Workaround :

    There is no known workaround at this time."
