Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm IBM InfoSphere Data Replication installationLocate the IBM InfoSphere Data Replication installation directory or check system inventory for IBM InfoSphere Data Replication 11.4.0 for z/OSAffected if IBM InfoSphere Data Replication 11.4.0 is installed and running
-
Verify the exact version numberCheck the installed version using IBM utilities or product documentation - look for version 11.4.0 specificallyAffected if The installed version is exactly 11.4.0 (no patches applied)
-
Determine if the log reading service is enabledReview the IBM InfoSphere Data Replication configuration to check if the remote source log reading service is active and listening for HTTP connectionsAffected if The log reading service is enabled and accessible via HTTP
-
Assess network exposure of the serviceCheck firewall rules, TCP listeners, or service bindings to determine if the log reading service port is exposed to untrusted network segmentsAffected if The log reading service port is accessible from untrusted or public network segments
A user is affected if they are running IBM InfoSphere Data Replication version 11.4.0 with the log reading service enabled and accessible to untrusted networks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply IBM-provided patches or updates for InfoSphere Data Replication 11.4. If patches are unavailable, implement network segmentation and restrict access to the log reading service to trusted sources only.
