Unauthenticated PHP code execution via routed function invocation
Published Jul 26, 2021 · Updated Aug 4, 2024
Remote code execution in Twothink 2.0 allows remote attackers to execute arbitrary PHP code through a crafted route request. The routeCheck path accepts the default s query parameter as PATH_INFO and dispatches a crafted route to think\app\invokefunction, which passes attacker-selected names and arguments to call_user_func_array. No authentication or user interaction is required, and successful exploitation runs attacker-selected PHP functions in the web application's execution context.
