Summary

NiceHash QuickMiner 6.12.0 perform software updates over HTTP without validating digital signatures or hash checks. An attacker capable of intercepting or redirecting traffic to the update url and can hijack the update process and deliver arbitrary executables that are automatically executed, resulting in full remote code execution. This constitutes a critical supply chain attack vector. NOTE: the Supplier reports that the existence of an http://update.nicehash.com URL is a fabrication, and that there is no other use of HTTP (rather than HTTPS).
