This has readline-like capabilities implemented in lua and has tab completion of expressions for interactive exploring the runtime. Prebuilt Binaries. While the lit method is quick and easy, we’re working on an even easier with pre-bundled luvit and lit binaries for popular platforms. As Egor said, os.execute has changed from lua 5.2 onwards. It now returns 3 value, and you can get the underlying process return code by looking at the third return value. However, it seems -- on Linux, at least --, that the return code is the same as what would "echo $?" provide (a value between 0 and 255). Let’s go for the reverse shell as root.

I added the nc reverse shell at the top of the script so the rev shell code can execute first.

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 … Lua reverse shell.

To test your install run luvit to enter the repl. This has readline-like capabilities implemented in lua and has tab completion of expressions for interactive exploring the runtime.

Okay!

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.

By default only globals from Lua standard library are defined; custom globals can be added using --globals CLI option or globals config option, and version of standard library can be selected using --std CLI option or std config option.

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")' Let’s go for the reverse shell as root.

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")'

I meant that I could get a reverse shell by exploiting the service, but I can't user and run the command sudo -* s*** /home/sysadmin/luvit *.lua Feb 11, 2021 os.execute("/bin/bash"). I placed this script as shell.lua in webadmin's directory and run: sudo -u sysadmin /home/sysadmin/luvit ./reverse.lua.
