CVE-2026-8175
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA buffer overflow vulnerability exists in the asperahttpd component of IBM Aspera High-Speed Transfer products (versions 3.7.4 through 4.4.7 Fix Pack 1). This memory corruption flaw in the HTTP daemon can be exploited to crash the service (DoS), bypass authentication mechanisms, or achieve remote code execution with elevated privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed IBM Aspera productDetermine whether the system runs IBM Aspera High-Speed Transfer Endpoint or Server. Check installed software listings, service descriptions, or product documentation on the host.Affected if The product is either IBM Aspera High-Speed Transfer Endpoint or Server.
-
Determine the installed version of the Aspera productLocate the installed version of IBM Aspera High-Speed Transfer software on the system. This is typically available via the software's About dialog, version info in the installation directory, or package management tools.Affected if The installed version is between 3.7.4 and 4.4.6 inclusive, or exactly 4.4.7.
-
Locate and verify the asperahttpd component versionIf available, query the specific version of the asperahttpd component directly. This may be found in component-level about info, service metadata, or the Aspera installation directory.Affected if The asperahttpd component version matches the affected product version range (3.7.4 through 4.4.7).
-
Confirm the asperahttpd service is runningCheck if the asperahttpd HTTP daemon service is active on the system. Use system service status commands or check process lists for asperahttpd.Affected if The asperahttpd service is currently running and the installed version falls within the affected range.
-
Inspect for crash logs or unexpected service behaviorReview system logs, Aspera-specific logs, and event logs for any crashes, restarts, or anomalous behavior related to asperahttpd. Check for any unexpected service interruptions.Affected if There are unexplained crashes or restarts of the asperahttpd service, or authentication anomalies that align with the vulnerability timeline.
A system is affected if it runs IBM Aspera High-Speed Transfer Endpoint or Server version 3.7.4 through 4.4.7 with the asperahttpd service active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply vendor-supplied patches for IBM Aspera High-Speed Transfer Endpoint and Server to versions beyond 4.4.7 Fix Pack 1. If patching is not immediately feasible, consider network segmentation or disabling the asperahttpd service if not required, and monitor for indicators of compromise.
Latest available Aspera Fix Pack beyond 4.4.7 Fix Pack 1 (e.g., 4.4.7 Fix Pack 2 or later)
- 1. Identify the current installed version of Aspera High-Speed Transfer Endpoint or Server using the asperaVersion command or checking the installation directory
- 2. Review IBM's official security bulletin at www.ibm.com for the specific patch or fixed version corresponding to CVE-2026-8175
- 3. If a newer Fix Pack (such as Fix Pack 2 or later) is available, download it from IBM Aspera support portal
- 4. Back up all Aspera configuration files and transfer data before applying the update
- 5. Apply the latest available Fix Pack following IBM's installation documentation
- 6. Restart the asperahttpd service after the update completes
- 7. Verify the service is running and test basic transfer functionality
- 8. Monitor IBM security notifications for any additional required updates
