FDsploit.py: Automatic (L|R)FI & directory traversal enumeration & exploitation.

Required (one of the following):
  -u , --url            Specify a url or
  -f , --file           Specify a file containing urls

Optional:
  -h, --help            Show this help message and exit
  -p , --payload        Specify a payload-file to look for [default None]
  -d , --depth          Specify max depth for payload [default 5]
  -e {0,1,2}, --urlencode {0,1,2}
                        Url-encode the payload [default: False]
  -t , --tchar          Use a termination character ('%00' or '?') [default None]
  -b, --b64             Use base64 encoding [default False]
  -x , --proxy          Specify a proxy to use [form: host:port]
  -c , --cookie         Specify a session-cookie to use [default None]
  -v , --verb           Specify request type ('GET' or 'POST') [default GET]
  --params  [ ...]      Specify POST parameters to use (applied only with POST requests)
                        Form: param1:value1,param2:value2,...
  -k , --keyword        Search for a certain keyword(s) on the response [default: None]
  -a, --useragent       Use a random user-agent [default user-agent: FDsploit_1.2_agent]
  --cmd                 Test for command execution through PHP functions [default command: None]
  --lfishell {None,simple,expect,input}
                        LFI pseudoshell [default None]

FDsploit can be used to discover and exploit Local/Remote File Inclusion and directory traversal vulnerabilities automatically. In case an LFI vulnerability is found, --lfishell option can be used to exploit it. For now, 3 different types of LFI shells are supported:

• simple: This type of shell allows user to read files easily without having to type the url everytime. Also it only provides the output of the file and not the whole html-source code of the page which makes it very useful.
• expect: This type of shell is a semi-interactive shell which allows user to execute commands through PHP's expect:// wrapper.
• input: This type of shell is a semi-interactive shell which also allows user to execute commands through PHP's php://input stream.

So far, there are only two lfi-shell built-in commands:

• clear and
• exit.

Features

• The LFI-shell interface provides only the output of the file readed or the command issued and not all the html code.
• 3 different types of LFI-shells can be specified.
• Both GET/POST requests are supported.
• Automatic detection of GET parameters.
• Certain parameters can be specified for testing using wildcards (*).
• Optional session cookies can be specified and used.
• Automatic check for RCE using PHP functions can be performed.
• Additional use of sha-256 hash is used to identify the potential vulnerabilities.
• base64/urlencoding support.

Some Examples

1. Directory traversal vulnerability discovery:

From the below output it seems that the directory parameter is probably vulnerable to directory traversal vulnerability since every request with ../ as payload produces a different sha-256 hash. Also the content-length is different for every request:

./fdsploit.py -u 'http://127.0.0.1:8888/test/bWAPP/bWAPP/directory_traversal_2.php?directory=documents' -c 'PHPSESSID=7acf1c5311fee614d0eb40d7f3473087; security_level=0' -d 8

2. LFI vulnerability discovery:

Again, the language parameter seems vulnerable to LFI since using ../etc/passwd etc.. as payload, every request being colored with green produces a different hash, a different content-length from the initial, and the keyword specified is found in the response:

./fdsploit.py -u 'http://127.0.0.1:8888/test/bWAPP/bWAPP/rlfi.php?language=*&action=go' -c 'PHPSESSID=7acf1c5311fee614d0eb40d7f3473087; security_level=0' -d 7 -k root -p /etc/passwd

3. LFI exploitation using simple shell:

Exploiting the above LFI using simple shell:

Notes

1. When POST verb is used, --params option must also be specified.
2. To test for Directory Traversal vulnerability the --payload option must be left to default value (None).
3. When --file options is used for multiple-urls testing, then only GET request is supported.
4. When both --file & --cookie options are set then since only one cookie can be specified each time the urls must refer on the same domain or be accessible without a cookie (that's is going to be fixed in a future update).
5. input shell is not compatible with POST verb.

Requirements:

Note: To install the requirements:

pip install -r requirements.txt --upgrade --user

💡 FDsploit also comes pre-installed with BlackArch Linux distribution.

TODO

• Fix note 4 from above and make --file also work with POST parameters and cookies, using probably a json etc... file as input.
• Add more built-in commands to --lfishell e.g. history etc...
