I am very pleased to see people building upon my Lua bytecode research, and I wouldn't be surprised to see more applications with embedded Lua which are exploitable like this.
it is a very good write up. it was not too difficult to convert it to 64 bit.
i'm fairly sure the demo page on the lua website is vulnerable: http://www.lua.org/demo.html but lua-5.3 is a little different fro lua-5.1 so i don't have a working exploit for this. but they let you load bytecode.
