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 potential denial of service in the asperahttpd component. An unauthenticated user can cause the asperahttpd service to crash.

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

A denial of service vulnerability exists 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 unauthenticated remote attacker can send specially crafted requests to cause the service to crash, resulting in availability disruption.

MitigationApply the vendor-supplied patch or upgrade to a fixed version of IBM Aspera High-Speed Transfer Endpoint/Server beyond 4.4.7 Fix Pack 1. Consider implementing network-level filtering to limit exposure to untrusted networks until the patch can be applied.

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. Verify asperahttpd component is installed
    Locate the asperahttpd binary or service on the system. Common paths include /opt/aspera/bin/asperahttpd or check system services for asperahttpd. Run 'ps aux | grep asperahttpd' or 'systemctl list-units | grep aspera' to confirm the service exists.
    Affected if The asperahttpd component is present and running on the system.
  2. Identify installed IBM Aspera product and version
    Check the installed version of IBM Aspera High-Speed Transfer Endpoint or Server. Run 'rpm -q aspera' or 'ls /opt/aspera' and inspect version files. Common commands include 'asession --version' or checking /opt/aspera/etc/aspera.conf for version information.
    Affected if The installed version is 3.7.4 through 4.4.6, or exactly 4.4.7.
  3. Confirm network exposure of asperahttpd service
    Determine if the asperahttpd service is listening on network interfaces accessible from untrusted networks. Run 'netstat -tlnp | grep asperahttpd' or 'ss -tlnp | grep asperahttpd' to identify bound IP addresses and ports. Check firewall rules and service configuration files for binding details.
    Affected if The asperahttpd service is bound to a network interface accessible from untrusted/external networks (e.g., 0.0.0.0 or public IP).
  4. Review service logs for crashes or restarts
    Examine system logs and aspera-specific logs for evidence of unexpected service crashes or restarts. Check /var/log/messages, /var/log/syslog, or /opt/aspera/logs/ for asperahttpd entries. Look for timestamps and error patterns indicating denial of service.
    Affected if Logs show repeated unexpected crashes or restarts of the asperahttpd service without corresponding admin intervention.

The system is affected if the asperahttpd component is running and the installed IBM Aspera High-Speed Transfer Endpoint or Server version falls within 3.7.4 through 4.4.6 or equals 4.4.7, with the service exposed to untrusted networks.

Upgrade available Upgrade to a release after 4.4.6
Interim mitigation

Apply the vendor-supplied patch or upgrade to a fixed version of IBM Aspera High-Speed Transfer Endpoint/Server beyond 4.4.7 Fix Pack 1. Consider implementing network-level filtering to limit exposure to untrusted networks until the patch can be applied.

Recommended fix Moderate confidence

IBM Aspera High-Speed Transfer Endpoint/Server 4.4.7 Fix Pack 2 or later

  1. 1. Identify the currently installed Aspera High-Speed Transfer Endpoint or Server version using the IBM Aspera administration tools or system inventory.
  2. 2. Download IBM Aspera High-Speed Transfer Endpoint or Server version 4.4.7 Fix Pack 2 or later from IBM Fix Central (https://www.ibm.com/support/fixcentral/).
  3. 3. Review IBM Aspera installation documentation for pre-upgrade requirements, including backing up configuration files and ensuring system prerequisites are met.
  4. 4. Stop the asperahttpd service before applying the upgrade to prevent potential data corruption.
  5. 5. Apply the upgrade package following IBM's standard upgrade procedure for Aspera products.
  6. 6. After installation, verify the asperahttpd service starts successfully and confirm the new version is running.
  7. 7. Test the Aspera transfer functionality to ensure normal operations have resumed.
