IBM Cognos Controller 10.4.1, 10.4.2, and 11.0.0 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic. IBM X-Force ID: 196640.
