Summary
IBM TXSeries for Multiplatforms 8.1, 8.2, 9.1, CICS TX Standard, 11.1, CICS TX Advanced 10.1, and 11.1 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: 257102.
