Unauthenticated control via spoofed loopback header
Published Apr 27, 2021 · Updated Aug 4, 2024
Authentication bypass in HomeAutomation 3.3.2 allows remote attackers to control smart-home devices through crafted HTTP requests. The login module calls isIpLocal(), whose getIpAddress() helper trusts X-Forwarded-For and treats any value beginning with 127. as local. No credentials or user interaction are required; the bypass creates an authenticated session exposing device controls and macros.
