Specifically, versions 3.7.4 through 4.4.7 Fix Pack 1 of both the Endpoint and Server products, along with the general Aspera High-Speed Transfer Endpoint, are susceptible to this flaw. The vulnerability lies within the asperahttpd component, where an unauthenticated user can trigger a crash of the service. This can disrupt file transfer operations and potentially impact overall system availability. The CVE ID associated with this vulnerability is CVE-2026-8180.

Attack Chain

  1. An unauthenticated attacker sends a crafted request to the asperahttpd service.
  2. The crafted request triggers a null pointer dereference within the asperahttpd component (CWE-476).
  3. The null pointer dereference causes the asperahttpd service to crash.
  4. The crash disrupts normal operation of the Aspera High-Speed Transfer Endpoint or Server.
  5. Users are unable to initiate or complete file transfers.
  6. Repeated exploitation leads to sustained denial of service.

Impact

Successful exploitation of CVE-2026-8180 results in a denial of service, impacting the availability of the Aspera High-Speed Transfer Endpoint and Server. This can disrupt critical file transfer workflows, potentially leading to data delivery delays and operational downtime. The number of affected systems depends on the number of deployments running the vulnerable versions.

Recommendation

  • Upgrade IBM Aspera High-Speed Transfer Endpoint and Server to a version beyond 4.4.7 Fix Pack 1 to remediate CVE-2026-8180, as recommended by the vendor advisory (https://www.ibm.com/support/pages/node/7273615).
  • Deploy the Sigma rule “Detect Asperahttpd Service Crash” to monitor for crashes related to potential exploitation attempts.
  • Monitor network traffic for anomalous requests targeting the asperahttpd service to identify potential exploitation attempts.
