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 broader networks or with large numbers of authenticated users. Security teams in media production, healthcare data exchange, financial services, and research institutions where Aspera is commonly deployed for high-volume file transfers.

Technical summary

The asperahttpd component in IBM Aspera High-Speed Transfer Endpoint 3.7.4-4.4.7 FP1 and IBM Aspera High-Speed Transfer Server 3.7.4-4.4.7 FP1 contains a stack-based buffer overflow (CWE-121). An attacker with valid credentials can send crafted HTTP requests to trigger memory corruption and achieve arbitrary code execution with the privileges of the asperahttpd process. The vulnerability is remotely exploitable with low complexity once authentication is obtained.

Defensive priority

high

Recommended defensive actions

  • Apply IBM Aspera High-Speed Transfer Endpoint/Server 4.4.7 Fix Pack 2 or later when available per IBM security bulletin guidance
  • Restrict network access to asperahttpd service to authorized administrative hosts only
  • Monitor asperahttpd process logs for anomalous crash events or unexpected restarts
  • Review authenticated user accounts and remove unnecessary privileges from Aspera service accounts
  • Deploy endpoint detection and response (EDR) rules targeting buffer overflow patterns in asperahttpd
  • Validate input sanitization on any custom integrations with Aspera HTTP API endpoints
