AI Analysis

Impact

The vulnerability arises from unchecked resource allocation in IBM Financial Transaction Manager, allowing a remote attacker to trigger a denial of service by exhausting available resources. This is a classic resource exhaustion flaw (CWE‑770). When triggered, the FTM service may become unresponsive, leading to interruption of transaction processing and overall system availability.

Affected Systems

The flaw affects IBM Financial Transaction Manager for RedHat OpenShift versions prior to 4.0.11.0, notably 4.0.6.0 and earlier. The product is deployed in RedHat OpenShift clusters as part of IBM’s Financial Transaction Manager offering. The advisory specifically mentions FTM 4.0.11.0 as the first fix.

Risk and Exploitability

The CVSS base score is 6.5, indicating a moderate severity and an available attack vector that appears to be remote. EPSS is not available, so exploitation probability is uncertain. The vulnerability is not listed in CISA’s KEV catalog. Attackers could remotely send crafted requests or trigger internal processes to force the FTM instance to allocate unlimited resources, causing a denial of service. Blocking such traffic or applying the patch reduces this risk.

Remediation

Vendor Solution

IBM strongly recommends addressing the vulnerabilities now by updating FTM deployments to the following Affected Product(s)Resolved by VRMFRemediation / First FixFinancial Transaction Manager (FTM) for RedHat OpenShift4.0.11.0 FTM 4.0.11.0 https://www.ibm.com/support/pages/node/7285661

OpenCVE Recommended Actions

  • Apply the IBM patch to upgrade Financial Transaction Manager to version 4.0.11.0 on your OpenShift cluster.
  • Configure OpenShift resource quotas and limits for the FTM deployment to cap CPU and memory usage, preventing uncontrolled resource consumption.
  • Deploy monitoring of FTM logs and resource metrics to detect sudden spikes in allocation that indicate potential denial‑of‑service attempts.
