CVE-2025-27579Public exploitNetwork attack vector

Payout diversion via unauthenticated cross-origin API

Published Mar 2, 2025 · Updated Mar 4, 2025

CSRF in Bitaxe ESP-Miner before 2.5.0 allows remote attackers to redirect mining payouts or alter device operating settings. The AxeOS web server accepts unauthenticated PATCH requests to /api/system with permissive CORS headers, allowing malicious web content to overwrite payout, frequency, and voltage values. Exploitation requires a browser on the miner's LAN to load malicious content; demonstrated effects are payout-address replacement and a miner restart.
