I assume you are just searching a running http webserver which doesn't need to be extendable, if not the following won't apply for you.
If there is Java installed on that machine you can use one of the many "single-file-webservers" that are out there. For example: https://github.com/NanoHttpd/nanohttpd
Or: http://www.eclipse.org/jetty/
If you have Node.js running you will find even more, very simply and efficient solutions.
