Who should care

Organizations running IBM Aspera High-Speed Transfer Endpoint or Server versions 3.7.4 through 4.4.7 Fix Pack 1, particularly those with asperahttpd exposed to untrusted networks or the internet. Security teams responsible for file transfer infrastructure and availability of critical data movement services.

Technical summary

The asperahttpd component in IBM Aspera High-Speed Transfer Endpoint and Server fails to handle certain input conditions, resulting in a NULL pointer dereference (CWE-476) that causes service termination. The vulnerability is reachable without authentication over the network, making it suitable for automated exploitation. The crash condition affects availability but does not provide confidentiality or integrity compromise.

Defensive priority

HIGH

Recommended defensive actions

  • Apply IBM Aspera High-Speed Transfer Endpoint or Server patches to version 4.4.7 Fix Pack 2 or later as indicated in the vendor security advisory
  • Restrict network access to asperahttpd service endpoints to authorized hosts only
  • Monitor asperahttpd service logs for unexpected crashes or restart events
  • Implement network segmentation to limit exposure of Aspera transfer services to untrusted networks
  • Review and validate that asperahttpd is not exposed directly to the internet without additional access controls
