AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
HTTP method-based constraint bypass is remotely reachable and requires no auth or interaction (AV:N/AC:L/PR:N/UI:N); unauthorized read and modification of transaction data give C:H/I:H, with no availability impact (A:N).

IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to perform unauthorized actions due to improper configuration of HTTP method-based security constraints.
AnalysisAI
IBM Financial Transaction Manager (FTM) for Red Hat OpenShift can be driven into performing unauthorized actions by remote, unauthenticated attackers because its HTTP method-based security constraints do not cover every verb, allowing requests that fall outside the configured constraint set to reach protected functions. The vendor CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, 9.1) and CWE-306 assignment confirm a low-complexity, network-reachable missing-authentication defect with high confidentiality and integrity impact and no availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the FTM for RedHat OpenShift application's protected endpoints and the ability to send requests with an HTTP method that the application's declarative security constraints fail to cover - the flaw is that security constraints are defined per-HTTP-method, so methods outside the constrained set bypass authentication/authorization. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely high-priority issue on paper: the vendor CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N (9.1) describes remote, unauthenticated, low-complexity exploitation with high confidentiality and integrity impact and no availability impact, consistent with CWE-306 (Missing Authentication for Critical Function) manifesting as an HTTP method-based security-constraint bypass (classic HTTP verb tampering). … 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 has released a fix for this issue, documented in the vendor advisory at https://www.ibm.com/support/pages/node/7288641 (patch available per vendor advisory); apply the IBM-supplied update for FTM for Red Hat OpenShift, since the provided data does not state an exact patched version number and the correct level must be read from that advisory before upgrading. … 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, identify which instances are internet-facing or reachable from untrusted networks, and immediately restrict inbound access to the application and its management interfaces using OpenShift routes, ingress controllers, or upstream firewalls; enable verbose HTTP access logging and review recent request logs for anomalous or unexpected HTTP verbs against protected endpoints. …
