Summary

CVE-2024-39743 is a medium-severity Amplification (CWE-405) vulnerability in Ibm Mq Operator. Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Denial of Service (T1498); ranked at the 45th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Adversaries may target the different network services provided by systems to conduct a denial of service (DoS).
T1499.003 Application Exhaustion Flood Impact
Adversaries may target resource intensive features of applications to cause a denial of service (DoS), denying availability to those applications.
T1498.002 Reflection Amplification Impact
Adversaries may attempt to cause a denial of service (DoS) by reflecting a high-volume of network traffic to a target.
T1499 Endpoint Denial of Service Impact
Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.
T1499.001 OS Exhaustion Flood Impact
Adversaries may launch a denial of service (DoS) attack targeting an endpoint's operating system (OS).

Mitigating Controls (NIST 800-53 r5) AI

SC-5 directly requires mechanisms to limit the effects of asymmetric resource exhaustion attacks such as amplification DoS.

SC-6 enforces resource quotas and priority allocation that reduce the impact of unauthenticated or low-effort resource requests.

Least-functionality disables unnecessary services or features that could be leveraged for amplification.

SC-7 boundary controls can filter or rate-limit traffic patterns that enable amplification without equivalent client work.

Resilience mechanisms such as rate limiting and load balancing directly constrain asymmetric resource use.

Capacity planning and monitoring maintain availability headroom against amplification attacks.

DE.CM-01 partial match
prevents

Network monitoring detects amplification traffic patterns but does not itself limit asymmetric consumption.

Runtime resource monitoring can surface excessive consumption yet does not enforce authorization or work proofs.
