This is a general problem that exists not just with HTTP Digest, but also with other IETF protocols that use tunneled authentication. This document specifies version 2 of the HTTP Digest AKA algorithm (RFC 3310). This algorithm can be implemented in a way that it is resistant to the man-in-the-middle attack.
