#Vulnerability
SideJacking is the process of sniffing web cookies, then replaying them to
clone another user's web session. Using a cloned web session, the jacker can
exploit the victim's previously-established site access

#Impact
This allows attackers that can read the network traffic to intercept all
the data that is submitted to the server or web pages viewed by the client.
Since this data includes the session cookie, it allows him to impersonate
the victim, even if the password itself is not compromised.



#Proof of concept

Probably i can't understeand. Is there truly someone so crazy to don't use
ssl for the owa access ? SSL stop sidejacking, and tool - nice FWIW - as
hamster and ferret just for example.
