Описание
Luanti (formerly Minetest) is an open source voxel game-creation platform. Starting in version 5.0.0 and prior to version 5.15.2, a malicious mod can trivially escape the sandboxed Lua environment to execute arbitrary code and gain full filesystem access on the user's device. This applies to the server-side mod, async and mapgen as well as the client-side (CSM) environments. This vulnerability is only exploitable when using LuaJIT. Version 5.15.2 contains a patch. On release versions, one can also patch this issue without recompiling by editing builtin/init.lua and adding the line getfenv = nil at the end. Note that this will break mods relying on this function (which is not inherently unsafe).
A flaw was found in Luanti (formerly Minetest), an open-source game platform. A malicious mod, when executed within the LuaJIT environment, can bypass security restrictions designed to isolate it. This allows the mod to execute unauthorized code and gain full access to the user's device, potentially leading to a complete system compromise.
Отчет
This vulnerability is only exploitable when using LuaJIT. You can use luanti --version to determine the type of Lua in use.
