Prior to 1.17.6, GuiServer::WndHookRegisterSlave in Sandboxie/core/svc/GuiServer.cpp stores attacker-supplied hthread and hproc fields from a GUI_WND_HOOK_REGISTER request without validating that the thread belongs to the sandboxed process or that the function pointer is in the caller address space, and GuiServer::WndHookNotifySlave then calls OpenThread(THREAD_SET_CONTEXT, FALSE, whk->hthread) and QueueUserAPC((PAPCFUNC)whk->hproc, hThread, (ULONG_PTR)req->threadid) as SYSTEM, allowing a sandboxed process to execute arbitrary code in an unsandboxed host process. This issue is fixed in version 1.17.6."

Antes de la versión 1.17.6, GuiServer::WndHookRegisterSlave en Sandboxie/core/svc/GuiServer.cpp almacena los campos hthread y hproc proporcionados por el atacante de una solicitud GUI_WND_HOOK_REGISTER sin validar que el hilo pertenezca al proceso en sandbox o que el puntero de función esté en el espacio de direcciones del llamador, y GuiServer::WndHookNotifySlave luego llama a OpenThread(THREAD_SET_CONTEXT, FALSE, whk  ->  hthread) y QueueUserAPC((PAPCFUNC)whk  ->  hproc, hThread, (ULONG_PTR)req  ->  threadid) como SYSTEM, permitiendo que un proceso en sandbox ejecute código arbitrario en un proceso anfitrión no en sandbox. Este problema está solucionado en la versión 1.17.6."
