Unauthenticated code execution via RMIServlet file upload
Published Oct 15, 2025 · Updated Oct 15, 2025
Unrestricted file upload in SmartBI V8, V9, and V10 allows remote attackers to execute arbitrary code through crafted RMIServlet requests. The RMIServlet path accepts attacker-controlled service and method selectors, while CheckIsLoggedFilter exempts selected calls before dispatching dangerous file operations. The path requires no authentication or user interaction, although exploitation depends on environment-specific attack requirements.
