Abstract

The ActiveSync protocol's implementation on some embedded devices leaves clients vulnerable to unauthorised remote policy enforcement. This paper discusses a proof of concept attack against the implementation of ActiveSync in common Smart phones including Android devices and iOS devices. A two-phase approach to exploiting the ActiveSync protocol is introduced. Phase 1 details the usage of a man-in-the-middle attack to gain a vantage point over the client device, whilst Phase 2 involves spoofing the server-side ActiveSync responses to initiate the unauthorised policy enforcement. These vulnerabilities are demonstrated by experiment, highlighting how the system can be exploited to perform a remote factory reset upon an Exchange-integrated Smart phone.
