Today's virtual switches not only support legacy network protocols and standard network management interfaces, but also become adapted to OpenFlow as a prevailing communication protocol. This makes them a core networking component of today's virtualized infrastructures which are able to handle sophisticated networking scenarios in a flexible and software-defined manner. At the same time, these virtual SDN data planes become high-value targets because a compromised switch is hard to detect while it affects all components of a virtualized/SDN-based environment.Most of the well known programmable virtual switches in the market are open source which makes them cost-effective and yet highly configurable options in any network infrastructure deployment. However, this comes at a cost which needs to be addressed. Accordingly, this paper raises an alarm on how attackers may leverage white box analysis of software switch functionalities to lunch effective low profile attacks against it. In particular, we practically present how attackers can systematically take advantage of static and dynamic code analysis techniques to lunch a low rate saturation attack on virtual SDN data plane in a cloud data center.
