Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 1.05% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs IBM MQ and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

IBM MQ and IBM MQ Appliance 9.1 CD, 9.1 LTS, 9.0 LTS, and 8.0 is vulnerable to a denial of service attack caused by channels processing poorly formatted messages. IBM X-Force ID: 166357.

What

IBM MQ and IBM MQ Appliance 9.1 CD, 9.1 LTS, 9.0 LTS, and 8.0 is vulnerable to a denial of service attack caused by channels processing poorly formatted messages. IBM X-Force ID: 166357.

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

What

IBM MQ and IBM MQ Appliance 9.1 CD, 9.1 LTS, 9.0 LTS, and 8.0 is vulnerable to a denial of service attack caused by channels processing poorly formatted messages. IBM X-Force ID: 166357.

Why

The current structured CVE record identifies a security weakness, but the root cause requires confirmation in the linked vendor material.

How

An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
