Technical details

A heap-based buffer overflow (CWE-122) exists in the asperahttpd component of IBM Aspera High-Speed Transfer Server and Endpoint. The vulnerability is reachable over the network without authentication (AV:N/AC:L/PR:N/UI:N). By sending specially crafted requests to the affected component, a remote attacker can trigger the overflow to cause a denial of service (service crash), bypass authentication mechanisms, or achieve arbitrary remote code execution (RCE) with the privileges of the asperahttpd process. IBM has released 4.4.7 Fix Pack 2 to address this issue.
