Impact
The vulnerability is a buffer overflow in the asperahttpd component of IBM Aspera High-Speed Transfer Endpoint and Server. Attackers could trigger the overflow to crash the service, causing denial of service. The flaw also permits authentication bypass or full remote code execution, compromising confidentiality, integrity, and availability. The weakness is a classic heap or stack overflow, identified as CWE-122.
Affected Systems
Affected are IBM Aspera High-Speed Transfer Endpoint and IBM Aspera High-Speed Transfer Server versions 3.7.4 through 4.4.7 Fix Pack 1. The recommended fix is to upgrade to version 4.4.7 Fix Pack 2 for both Endpoint and Server, which addresses the buffer overflow.
Risk and Exploitability
With a CVSS score of 9.8, this is a critical vulnerability. No EPSS score is available, but the lack of KEV listing does not reduce the urgency. The flaw can be exploited remotely over the network by sending crafted requests to asperahttpd, likely without authentication. Attackers could achieve full remote code execution or related privileges, making this a high-risk exposure that should be remediated immediately.
