Some web sites transmit authentication material (often cookies) without encrypting the entire session, even when the authentication material is initially set over an encrypted HTTP session. This behavior could allow an attacker on the network path to obtain authentication material and impersonate a legitimate user. Sites that set authentication cookies over https during login and then later transmit the cookies over HTTP are particularly vulnerable, since users are more likely to think that the security of the login page applies to the entire session.","title":"Summary"},{"category":"legal_disclaimer","text":"THIS DOCUMENT IS PROVIDED ON AN 'AS IS' BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
