CVE-2022-34313Network attack vector

Application-session access via missing cookie Secure attribute

Published Nov 14, 2022 · Updated Apr 30, 2025

Information disclosure in IBM CICS TX Standard and Advanced allows remote attackers to steal session cookies through cleartext HTTP. Authorization tokens and session cookies are created without the Secure attribute, so a browser sends them to an attacker-controlled HTTP link. Exploitation requires user interaction and an attacker positioned to snoop the resulting unencrypted traffic; a captured token grants access to the associated application session.
