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 Aspera High-Speed Transfer Endpoint 3.7.4 through 4.4.7 Fix Pack 1 and IBM Aspera High-Speed Transfer Server 3.7.4 through 4.4.7 Fix Pack 1 and IBM Aspera High-Speed Transfer Endpoint are affected by a buffer overflow in the asperahttpd component. This vulnerability could allow an authenticated user to execute arbitrary code on the system.

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 · high confidence

Buffer overflow vulnerability in the asperahttpd component of IBM Aspera High-Speed Transfer Endpoint and Server versions 3.7.4 through 4.4.7 Fix Pack 1. An authenticated user can exploit this to execute arbitrary code on the system, potentially leading to complete system compromise.

MitigationUpgrade to a patched version of IBM Aspera High-Speed Transfer Endpoint/Server beyond 4.4.7 Fix Pack 1. If immediate patching is not possible, restrict access to the asperahttpd service to only trusted, authorized users and monitor for suspicious activity.

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. Identify if IBM Aspera is installed
    Look for the Aspera installation directory (commonly in /opt/aspera or C:\Program Files\Aspera) or check for the asperahttpd process using task manager or ps command
    Affected if The software is not found, this CVE does not apply
  2. Determine the installed version
    Check the version file in the Aspera installation directory, or run 'asnp --version' or check the application properties/about page
    Affected if Version cannot be determined or is not in the IBM Aspera product line
  3. Compare version to affected range
    Verify the version falls within 3.7.4 through 4.4.7 inclusive, or is 4.4.7 Fix Pack 1
    Affected if Version is 3.7.4, 3.9.x, 4.0.x, 4.1.x, 4.2.x, 4.3.x, 4.4.0 through 4.4.6, or exactly 4.4.7 (any fix pack)
  4. Confirm asperahttpd component is in use
    Check if the asperahttpd service is running or enabled, typically visible in service status or process list
    Affected if asperahttpd is not present or not running (vulnerability only applies when this component is active)

You are affected if IBM Aspera High-Speed Transfer Endpoint or Server version is between 3.7.4 and 4.4.7 (inclusive) or exactly 4.4.7, and the asperahttpd component is installed and running.

Upgrade available Upgrade to a release after 4.4.6
Interim mitigation

Upgrade to a patched version of IBM Aspera High-Speed Transfer Endpoint/Server beyond 4.4.7 Fix Pack 1. If immediate patching is not possible, restrict access to the asperahttpd service to only trusted, authorized users and monitor for suspicious activity.

Recommended fix Moderate confidence

Aspera High Speed Transfer Endpoint/Server version 4.4.7 Fix Pack 2 or latest available version

  1. 1. Identify the current installed version of Aspera High Speed Transfer Endpoint or Server using the system administration console or version check command.
  2. 2. Download the latest version of Aspera High Speed Transfer Endpoint or Server from IBM's official Aspera support portal (https://www.ibm.com/support/pages/aspera)
  3. 3. Review IBM Aspera release notes for version 4.4.7 Fix Pack 2 or later to confirm the security fix for CVE-2026-8179 is included
  4. 4. Schedule a maintenance window as the upgrade may require service interruption
  5. 5. Back up current configuration and database files before proceeding with the upgrade
  6. 6. Install the upgrade following IBM's standard upgrade procedures for Aspera products
  7. 7. Verify the asperahttpd component version after upgrade confirms the fix is applied
  8. 8. Test the functionality to ensure normal transfer operations work after the upgrade
Caveat Review IBM release notes for any configuration changes or deprecated features between your current version and the target version; test in non-production environment first
