Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Remote low-complexity unauthenticated input triggers the reflection flaw (AV:N/AC:L/PR:N/UI:N); impact is availability-only DoS, so C:N/I:N/A:H with unchanged scope.

IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to cause a denial of service due to the improper use of reflection with externally controlled input.
AnalysisAI
Denial of service in IBM Financial Transaction Manager (FTM) for Red Hat OpenShift: unsafe reflection handling of externally controlled input lets an unauthenticated remote attacker (CVSS 3.1 AV:N/AC:L/PR:N/UI:N) drive the service into an availability failure, scored A:H with no confidentiality or integrity impact for a base score of 7.5. Deployments affected are the 4.0.6.x through 4.0.10.0 releases listed by IBM prior to the Interim Fix 064 level. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to an IBM Financial Transaction Manager (FTM) for RedHat OpenShift instance that processes externally controlled input routed through a reflection operation (CWE-470); per the CVSS vector (AV:N/AC:L/PR:N/UI:N) no authentication or user interaction is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are largely consistent and point to a genuine but moderate-priority availability issue. … 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 | IBM indicates a patch is available from the vendor, and the affected-version data identifies 4.0.10.0 Interim Fix 064 as the fixed level for the 4.0.10.0 branch; apply the corresponding fix from the IBM advisory at https://www.ibm.com/support/pages/node/7288641 and confirm the FTM operator/image builds are at or above that level after rollout (the advisory should be consulted for the exact fix for each affected 4.0.6.x-4.0.9.0 line, since only the 4.0.10.0 Interim Fix 064 level is named in the provided data). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every IBM Financial Transaction Manager for Red Hat OpenShift deployment to determine which instances run releases 4.0.6.x through 4.0.10.0 below Interim Fix 064, and confirm whether any are reachable from untrusted networks rather than only from inside controlled OpenShift clusters; where internet-facing or broadly reachable, restrict network access to trusted sources and increase availability monitoring and restart alerting as an interim measure. …
