IBM CICS Transaction Server 3.1, 3.2, 4.1, 4.2, and 5.1 on z/OS does not properly implement CEMT transactions, which allows remote authenticated users to cause a denial of service (storage overlay) by using a 3270 emulator to send an invalid 3270 data stream.

Security readout for executives and security teams

This issue affects older IBM CICS Transaction Server releases on z/OS. An authenticated remote user could trigger a denial of service by sending malformed 3270 terminal data, potentially disrupting transaction processing on systems that still run affected CICS versions. Exposure is most likely in legacy z/OS environments still running the listed CICS Transaction Server versions and permitting authenticated 3270 access to CICS transaction interfaces. Treat this as a legacy-platform availability risk. It is not described as unauthenticated or data-theft capable, but disruption to CICS can affect critical business transaction processing. Mitigation focus: Identify CICS Transaction Server versions 3.1, 3.2, 4.1, 4.2, and 5.1 on z/OS.; Review IBM APARs PI16710, PI16726, and PI16727 for official fix or maintenance guidance.; Restrict 3270/CICS access to authorized users and trusted network paths..
