Shell. It can be used to break out from restricted environments by spawning an interactive system shell. lua -e 'os.execute("/bin/sh")' Non-interactive reverse shell. It can send back a non-interactive reverse shell to a listening attacker to open a remote network access. Run nc -l -p 12345 on the attacker box to receive the shell.

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

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. More Googling lead me to GTFObins. The shell command that they mention is: lua -e 'os.execute("/bin/sh")' --Evaluate special segments in reverse order. local skip = 0: local reversed = {} for idx = # parts, 1, -1 do: local part = parts[idx] if part == '. ' then--Ignore: elseif part == '..

Let’s execute the shell. Voila! Considering the note mentioning the script language lua i suspect that the binary has something to do with lua. From the luvit blog we can read the following. Luvit is a single binary that contains the lua vm, libuv, openssl, miniz as well as a host of standard libraries implemented in lua that closely resemble the public node.js APIs.

--Evaluate special segments in reverse order. local skip = 0: local reversed = {} for idx = # parts, 1, -1 do: local part = parts[idx] if part == '. ' then--Ignore: elseif part == '.. ' then: skip = skip + 1: elseif skip > 0 then: skip = skip -1: else: reversed[# reversed + 1] = part: end: end--Reverse the list again to get the correct order: parts = reversed: for idx = 1, # parts / 2 do

lua: os.execute('/bin/sh')From within IRB: Jun 29, 2020 My objective now was to set up a reverse shell.

Since Lua is an interpreted/compiled language that its own compilers and isn't usually translated/compiled with a C compiler. What tools should be used to reverse …

Lua (/ ˈ l uː ə / LOO-ə; from Portuguese: lua meaning moon) is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications.

This simple web server written in Luvit responds with Hello World for every request. 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.

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.

This requires that rview is compiled with Python support.

We see that we can use sudo without password on user sysadmin for /home/sysadmin/luvit, Luvit is the tool which is used to practise Lua. We created a Lua one liner script which will help us get reverse shell and then we run the script through Luvit so that we can get our reverse shell as sysadmin. We got reverse shell as Sysadmin user

In most cases, you just want to install lit as quickly as possible, possibly in a Makefile or make.bat in your own library or app.
