Exploiting Lua 5.1 on 32-bit Windows

The following Lua program generates a Lua bytecode program called ignore-unsigned-sga.fnt, which in turn loads a DLL from within an extremely locked down Lua 5.1 sandbox in a program called RelicCOH2.exe. The remainder of this document attempts to explain how this program works by a whirlwind tour of relevent bits of the Lua 5.1 virtual machine.

if string.dump(function()end):sub(1, 12) ~= "\27Lua\81\0\1\4\4\4\8\0" then
  error("This generator requires a 32-bit version of Lua 5.1")
end

local function outer()
  local magic -- In bytecode, the stack slot corresponding to this local is changed

Nestable, sortable and dragable categories:

In the project I'm working on we wanted to have a Category model which we wanted to be nestable. But we also liked the user to have a draggable interface to manage and rearrange the order of his categories. So we chose awesome_nested_set for the model and jQuery.nestedSortable for the UI.

It took me some time to arrange things to work properly so I wanted to share my work in case it helps anybody.
