CVE-2023-22809: sudoedit (aka sudo -e) exploit

My preferred editor is Helix, hence the hx command. You could use Vim or something as well. This exploit works because I allowed the centdemeern1 account access to editing this file in the /etc/sudoers file, with this line:

centdemeern1 ALL=(ALL) NOPASSWD: sudoedit /root/accessible.txt

You can replay the downloaded recording in your terminal using the asciinema play command:

If you don't have asciinema CLI installed then see installation instructions.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>

<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/560404.cast',
      document.getElementById('player'),
      { cols: 188, rows: 49 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/560404 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
