I think you are looking for
glGetIntegerv(GL_FRAMEBUFFER_BINDING_EXT).

If it returns 0, then it refers to the window-system-provided (default) framebuffer.
If non-zero value is returned, then it refers to the currently bound FBO.

Other tokens added for FBO extension are;
GL_RENDERBUFFER_BINDING_EXT
GL_MAX_COLOR_ATTACHMENTS_EXT
GL_MAX_RENDERBUFFER_SIZE_EXT

Also, please check FBO specific interfaces to get info of the bound FBO;
glGetFramebufferAttachmentParameterivEXT()
glGetRenderbufferParameterivEXT()
