DescriptionCVE.org

IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to execute unauthorized payment actions due to missing authorization checks.

AnalysisAI

Missing authorization checks in IBM Financial Transaction Manager (FTM) for Red Hat OpenShift let unauthenticated attackers execute unauthorized payment actions against the payment-action interface, compromising transaction integrity with a limited availability impact (CVSS 3.1 base 7.1, CWE-862). The assessed vector (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L) means the attacker must already sit on an adjacent network - the same LAN segment, an established VPN, or the OpenShift cluster/service-mesh network - rather than reaching the service from the open Internet, so exposure is bounded by network placement even though no credentials or user interaction are required. …

Vulnerability AssessmentAI

Exploitation Requires the attacker to reach the FTM for RedHat OpenShift payment-action interface from an adjacent network position (AV:A) - same LAN segment, VPN, or OpenShift cluster/service-mesh network - not arbitrary Internet reach. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but moderate-priority integrity issue rather than an inflated high-CVSS finding. … 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 for IBM Financial Transaction Manager for Red Hat OpenShift per IBM's support advisory at https://www.ibm.com/support/pages/node/7288641 - IBM reports patch availability from the vendor, but no exact fix version or release identifier is included in the data provided here, so obtain the specific APAR/fix level and target version directly from that advisory before scheduling the upgrade. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, confirm whether IBM Financial Transaction Manager for Red Hat OpenShift is deployed anywhere in the estate (including pre-production and sandbox clusters used for payment testing), inventory each instance and its installed release level, and immediately tighten reachability of the payment-action interface using OpenShift NetworkPolicies, service-mesh authorization policies, or firewall rules so that only trusted internal segments and specific service accounts can reach it; prioritize applying the IBM-published fix to any instance reachable from broader internal networks. …
