DescriptionNVD

IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to read arbitrary files due to improper path canonicalization.

AnalysisAI

Path traversal in IBM Financial Transaction Manager (FTM) for Red Hat OpenShift, affecting builds from 4.0.6.0 through 4.0.10.0 Interim Fix 06 (Operator 4.4.6+20260807.081800), allows an unauthenticated remote attacker (PR:N/UI:N per the CVSS vector) to submit manipulated path input that the product fails to canonicalize and thereby read arbitrary files accessible to the FTM process. The impact is confidentiality-only - no write, code execution, or availability effect - and exploitation requires network reachability to the FTM application endpoint, so internal-only routes or network segmentation materially reduce exposure. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network reachability to the IBM Financial Transaction Manager (FTM) for RedHat OpenShift application endpoint and the ability to submit a request with manipulated path input that the application fails to canonicalize (CWE-22). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals are consistent and point to a moderate, not urgent, priority. … 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 The primary fix is the vendor patch: IBM published remediation information for this issue on its support site, and the correct action is to upgrade the affected FTM for Red Hat OpenShift deployment (and its 4.4.6+20260807.081800 Operator) to the corrected Refresh/Interim Fix level specified in IBM's advisory at https://www.ibm.com/support/pages/node/7288641, confirming the exact fixed build with IBM since the public version list only enumerates affected levels (4.0.6.0 through 4.0.10.0 Interim Fix 064). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify every IBM FTM for Red Hat OpenShift deployment at build 4.0.6.0 through 4.0.10.0 Interim Fix 06 (Operator 4.4.6+20260807.081800) using your OpenShift inventory and container image registry, and confirm whether the FTM application endpoint is reachable from untrusted networks or only from internal segmented routes; if any instance is internet-facing, restrict it at the ingress/route or network policy layer to trusted sources immediately. …
