CVE-2026-8179

IBM · Aspera High-Speed Transfer

A stack-based buffer overflow in the IBM Aspera High-Speed Transfer component allows authenticated attackers to execute arbitrary code.

Executive summary

A buffer overflow vulnerability in IBM Aspera High-Speed Transfer products allows authenticated attackers to compromise the host system through crafted input.

Vulnerability

The vulnerability is a stack-based buffer overflow (CWE-121) within the asperahttpd component, which can be triggered by sending specially crafted input to the service.

Business impact

Successful exploitation results in arbitrary code execution on the underlying host, impacting the confidentiality, integrity, and availability of the file transfer service. Given the CVSS score of 8.8, this represents a significant risk to high-value data transfer environments.

Remediation

Immediate Action: Upgrade to the latest version, specifically Fix Pack 2, as recommended by the vendor.

Proactive Monitoring: Review logs for anomalous HTTP traffic directed at the Aspera service and monitor for unexpected process behavior or service crashes.

Compensating Controls: Use network segmentation to restrict access to the Aspera interface to trusted IP addresses and employ an Intrusion Prevention System (IPS) to detect buffer overflow attempts.

Exploitation status

Public Exploit Available: false

Analyst recommendation

IBM Aspera administrators should prioritize the installation of Fix Pack 2. Given the potential for full system compromise, patching should be scheduled as a high-priority task to maintain the security of file transfer infrastructure.
