Code execution via unverified HTTP updates
Published Sep 30, 2025 · Updated Sep 30, 2025
Insecure updating in NiceHash QuickMiner 6.12.0 allows man-in-the-middle attackers to execute arbitrary code through a forged update. The cited disclosure says the updater retrieves update.json and its executable over HTTP, then runs the binary without checking a signature or cryptographic hash. Exploitation requires control of DNS or the network path; NiceHash disputes the report, stating that the cited HTTP URL is fabricated and QuickMiner uses HTTPS.
