# nanocmshell ⭐

a simple script that exploits an authenticated file upload/remote code execution vulnerability in NanoCMS v0.4.  

## the exploit ❗

https://github.com/kalyan02/NanoCMS has not been maintained in a long time and suffers from a a number of vulnerabilities including authenticated file upload/remote code execution which this script exploits.  

More information here: https://github.com/ishell/Exploits-Archives/blob/master/2009-exploits/0904-exploits/nanocms-multi.txt  

NanoCMS saves pages both new and edited, as .php files by default, allowing an authenticated attacker to upload executable code.  

this script uploads a webshell.

## prerequisites ✔

* python3

* python3 requests module

* python3 beautifulsoup4 module

```

sudo apt install python3

sudo apt install python3-pip

pip3 install beautifulsoup4

pip3 install requests

```

## usage ℹ

use `./nanocmshell` or `python3 nanocmshell` with `-h` or `--help` for help menu:

```

usage: nanocmshell [-h] [-u USER] [-p PASSWD] [-e] [-a] [-n] address file

../nanocmshell exploits authenticated file upload

and remote code execution in NanoCMS.

positional arguments:

  address               schema/ip/hostname, port, sub-directories to the vulnerable NanoCMS

                        server

  file                  php file to upload

options:

  -h, --help            show this help message and exit

  -u USER, --user USER  username

  -p PASSWD, --passwd PASSWD

                        password

  -e, --execute         attempts to make a request to the uploadedfile (more useful if

                        uploading a reverse shell)

  -a, --accessible      turns off features which may negatively affect screen readers

  -n, --no-colour       removes colour output

examples:

        python3 nanocmshell http://10.10.10.10/ rev.php

        python3 nanocmshell http://hostname:8080 rev-shell.php -a

        ./nanocmshell https://10.10.10.10 rev-shell -n -e -u 'user'

```

note: admin/demo are default credentials used but new ones can be supplied with `-u` and `-p` flags.

## notes 📝

the script was mainly an exercise in creating a comprehensive program for a single exploit with both readability and accessibility in mind.  

aims to handle a number of potential errors to make troubleshooting easier.  

probably unlikely to see this in the wild (as of 2022), but maybe useful for CTFs.
