The prefix for all commands is ./, just like running a local command in your shell. To run the bot, you'll need Discordia and Luvit installed. Then navigate to the directory with main.lua and run luvit main.lua. TODO: create proper help function; add ./clap command for memes

We also know that he mentioned about practicing lua — which is a programming language. So, if we create a lua script file to execute a reverse shell using the ‘luvit’ tool, we should be able to get Traceback was an easy rated Linux machine that required finding a webshell on an already pwned website, using it to upload a php reverse shell, then catching a shell as webadmin. From there, webadmin had access to running luvit as sysadmin so a simple Lua script was used to catch a reverse shell as sysadmin. Finally, lax permissions on motd files allowed me to append reverse shell code to catch a shell as root.
You have to enter a shell planted on the server enter as webadmin escalate privileges with lua luvit to sysadmin and echo a reverse shell in 00 header file to get
We got reverse shell as Sysadmin user 2. Get Root Flag via Reverse Shell. 1. Start a listener on local kali machine nc -nlvp 5555 2. luvit is a command line tool that doubles as a scripting platform similar to node but is written in Lua and allows us to run Lua functions/scripts. Here we use the 'execute' function in Lua's OS library, which will run whatever command we pass as an argument.
This is a list of libraries implemented in Lua or implemented in another language (e.g. C) but having a Lua interface. For older libraries and bindings, see the LuaAddonsArchive.. Modules can also be found on LuaForge.Lua ModuleReview intends to arrange some of them..

We maintain several binary releases of luvi to ease bootstrapping of lit and While in a Linux terminal on a virtual machine, I came across a need to get a bash shell on a particular user, running Luvit repl. I had never previously heard of the program and found very little documentation on it, none of which looked anything like what was shown in the terminal. The image above shows that I can run something called luvit. That prompted more googling and trying to understand whats going on. Here is a link if you are interested what Luvit is: https://luvit.io/ So now I needed to exploit that somehow.
We got reverse shell as Sysadmin user successfully and now moving onto getting user flag.

In this article, you’ll learn how this attack works and how you can detect it using Falco, a CNCF project, as well as Sysdig Secure.. Sometimes, an application vulnerability can be exploited in a way that allows an attacker to establish a reverse shell connection, which grants them interactive access to the system.

(5.1) - a Lua module and console application to create Windows NT administration and logon scripts. LuaExpect lists Lua implementations of the famous tool Logging libuv bindings for luajit and lua 5.1/ 5.2/ 5.3. This library makes libuv available to lua scripts. It was made for the luvit project but should usable from nearly any lua project. The library can be used by multiple threads at once. Each thread is assumed to load the library from a different lua_State.

Lua offers a higher-level function to load and run libraries, called require.Roughly, require does the same job as dofile, but with two important differences.First, require searches for the file in a path; second, require controls whether a file has already been run to avoid duplicating the work. Because of these features, require is the preferred function in Lua Reverse shell is a way that attackers gain access to a victim’s system.
