WLCCP - Analysis of a Potentially Flawed Protocol

<p>The world of "Enterprise WLAN solutions" is full of obscure and "non-standard" elements and technologies. One prominent example is Cisco's Structured Wireless-Aware Network (SWAN) architecture, composed of autonomous access points combined with some components for centralized management, and still deployed in a number of corporate networks. The proprietary "Wireless LAN Context Control Protocol" (WLCCP) plays a major role here. Unfortunately it seems the design of the protocol might be debatable in several aspects, leading to some theoretical and, well, practical vulnerabilities.In this talk we will describe the inner workings of this piece, dissect the vulnerable parts and have some discussion on good or bad protocol design. As usual, some demos will add spice and some code will be released.</p>
