DescriptionNVD

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 be exploited to cause a denial of service and potentially lead to authentication bypass or remote code execution.

AnalysisAI

Remote code execution and authentication bypass are possible in IBM Aspera High-Speed Transfer Server and High-Speed Transfer Endpoint (versions 3.7.4 through 4.4.7 Fix Pack 1) through a heap-based buffer overflow in the asperahttpd component. An unauthenticated network attacker can corrupt memory to crash the service (denial of service) and, in the worst case, hijack execution flow to run arbitrary code or bypass authentication. …

RemediationAI

24 hours: Complete inventory of all IBM Aspera deployments identifying affected versions (3.7.4-4.4.7 Fix Pack 1); immediately implement network access controls restricting connectivity to asperahttpd services. 7 days: Deploy intrusion detection rules, disable non-essential remote management, enable full audit logging on Aspera components, and restrict administrative access. …
