Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
IBM MQ Appliance 9.3 LTS, 9.3 CD, and 9.4 LTS web console could allow an authenticated user to cause a denial-of-service when trace is enabled due to information being written into memory outside of the intended buffer size.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Buffer overflow vulnerability in IBM MQ Appliance web console versions 9.3 LTS, 9.3 CD, and 9.4 LTS. When trace is enabled, an authenticated user can cause the web console to write information outside the intended buffer boundary, resulting in a denial-of-service condition.

MitigationApply IBM's security patch for this vulnerability. If immediate patching is not possible, consider disabling trace functionality in the web console as a compensating control until the patch can be applied.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm IBM MQ Appliance is in use
    Access the IBM MQ Appliance web console login page or check the system documentation to verify the product is IBM MQ Appliance. Alternatively, log into the appliance via SSH and run 'show version' to confirm the product name.
    Affected if The product is not IBM MQ Appliance (this CVE only affects the Appliance, not other IBM MQ deployments)
  2. Determine the installed version
    Log into the IBM MQ Appliance web console and navigate to the About or Version information page. From the CLI, run 'show version' to display the exact version number.
    Affected if The installed version falls within 9.3.0.0 through 9.3.0.26, or 9.4.0.0 through 9.4.0.7 (all versions up to and including 9.4.0.7)
  3. Verify trace functionality status in the web console
    Log into the IBM MQ Appliance web console as an authenticated user. Navigate to the diagnostic or trace settings area (typically under Advanced Settings, Troubleshooting, or Diagnostic settings). Check whether trace is currently enabled or disabled.
    Affected if Trace is enabled in the web console - this is the required condition for the buffer overflow to be triggerable

A user is affected if they are running IBM MQ Appliance versions 9.3.0.0-9.3.0.26 or 9.4.0.0-9.4.0.7 AND have trace functionality enabled in the web console.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 9.4.0.7
Interim mitigation

Apply IBM's security patch for this vulnerability. If immediate patching is not possible, consider disabling trace functionality in the web console as a compensating control until the patch can be applied.

Recommended fix Moderate confidence

IBM MQ Appliance 9.3.0.27+ (LTS) or 9.4.0.8+ (LTS), or latest 9.4.x LTS release

  1. 1. Identify the currently installed IBM MQ Appliance version using the CLI command: 'mqappliance version' or via the web console under Administration > System information
  2. 2. If running 9.3 LTS (9.3.0.0 through 9.3.0.26), upgrade to 9.3.0.27 or later LTS release
  3. 3. If running 9.4 LTS (9.4.0.0 through 9.4.0.7), upgrade to 9.4.0.8 or later LTS release
  4. 4. If running 9.3 CD (Continuous Delivery), upgrade to the latest 9.3 CD release or consider migrating to the 9.4 LTS track
  5. 5. Download the fix from IBM Fix Central (https://www.ibm.com/support/fixcentral) or obtain via IBM entitled licensing
  6. 6. Follow IBM's standard upgrade procedure for MQ Appliance - typically via the mqupgradecommand or through the web console's Software Update function
  7. 7. After upgrade, verify the new version is installed: 'mqappliance version'
  8. 8. Test that the web console is accessible and functioning normally
Caveat Standard IBM MQ Appliance upgrade - review IBM MQ Appliance release notes for any configuration or behavioral changes between versions; LTS to LTS upgrades are typically non-breaking
