Unauthenticated administrative access via unprotected web pages
Published May 20, 2026 · Updated May 20, 2026
Authentication bypass in Taiko AG1000-01A SMS Alert Gateway Rev 7.3 and Rev 8 allows remote attackers to gain administrative access. The embedded web interface serves index.zhtml, point.zhtml, and log.shtml directly without session management or server-side authentication checks. Network reachability alone is sufficient to read and change alarm routing and device configuration and to interrupt monitoring and control functions.
