DescriptionNVD

IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to perform unauthorized actions due to improper authentication and missing authorization.

AnalysisAI

Remote, unauthenticated attackers who can reach the application endpoints of IBM Financial Transaction Manager (FTM) for Red Hat OpenShift can perform unauthorized actions because the software fails to properly authenticate requests and subsequently omits authorization checks. Affected deployments are those running versions 4.0.6.0 through 4.0.10.0 Interim Fix 064, including Operator 4.4.6+20260807.081800 and the 4.0.6.0 Refresh build, per the EUVD version list. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network reachability to the FTM for RedHat OpenShift application endpoints, which in most deployments sit on internal or restricted financial-processing networks rather than the public internet - this network exposure is the primary realistic limiting factor. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a moderate-priority issue whose signals are largely consistent but point to limited current risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the vendor fix from IBM's advisory at https://www.ibm.com/support/pages/node/7288641 - IBM lists a patch as available from vendor, so organizations running FTM for Red Hat OpenShift 4.0.6.0 through 4.0.10.0 Interim Fix 064 should upgrade to the remediated build or interim fix named in that advisory and validate the update through their OpenShift operator subscription channel; patch availability is confirmed but no specific fixed version number is stated in the source data, so the exact target release must be read from the IBM support page rather than assumed. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all IBM FTM for Red Hat OpenShift deployments running versions 4.0.6.0 through 4.0.10.0 Interim Fix 064, including Operator 4.4.6+20260807.081800 and the 4.0.6.0 Refresh build, and restrict network access to application endpoints using firewall rules or network policies. …
