Portal
------------------------------------------------------------------------
Han Sahin, November 2014

------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
It was discovered that the session tokens in EMC Secure Remote Services
Virtual Edition are Base64 encoded XML tokens that lack any
cryptographic protection. Due to this it is possible for attackers to
create their own session cookies. Attackers with network access
(insiders) to the ESRS Web Portal can exploit this issue to gain
unauthorized access to the management interface.
