readloud/cve-2017-5638This script is intended to validate Apache Struts 2 vulnerability (CVE-2017-5638), AKA Struts-Shock.
This script is intended to validate Apache Struts 2 vulnerability (CVE-2017-5638), AKA Struts-Shock. This is a completely harmless as it does not inject any malicious payload, only inject an HTTP header named 'STRUTS2-VALIDATION' in order to be able to validate whether is vulnerable
Because of its multithread capability, it's able to run 2.5k+ applications spread around the globe in less than 10 minutes. So, it can be very handy to validate enterprise applications in large scale.

This project aims to demonstrate the CVE-2017-5638 exploitation for educational purpose. For more informations, see https://cwiki.apache.org/confluence/display/WW/S2-045
This project is made for educational and ethical testing purposes only. Attacking targets without prior mutual consent is illegal. It is the end user's responsibility to obey all applicable local, state and federal laws. Developers assume no liability and are not responsible for any misuse or damage caused by this program.
docker run -d -p 8080:8080 jrrdev/cve-2017-5638:latest
Download the exploit script on the attacker machine here
Run the python exploit script from the attacker machine :
python exploit.py http://<DOCKER_HOST>:8080/hello "ls -l"
There are two ways to run this script, with and without threading, the only difference will the execution time. To enable the threading feature, just need to pass the thread parameter.
The first parameter must be a TXT file containing all targeted URL, one per line. Please note that these URL should be complete, for example, https://target.com/admin/myStrutsPage.action
Here is a usage example without threading:
struts-shock-validation.py target_urls.txt
Now using threads capability:
struts-shock-validation.py target_urls.txt thread
Metasploit Framework Exploit Module for Apache Struts Content-Type exploit Have not tested against a windows server but tested against a linux server using the payload of generic/shell_bind_tcp
Example PoC Code for CVE-2017-5638 | Apache Struts Exploit | DORK: ext:action
USAGE: python struts.py https://victim.site dir
The initial Python Script that was Posted didn't correctly format the Content-Type Header. I recoded the Content Type Header to properly format Content-Type:%20{Exploit}. I also added a logging and Requests, then dumped the Object Properties to stdout.
SAMPLE OUTPUT
Check for CVE-2017-5638 by XSS.Cx
Volume in drive D has no label. Volume Serial Number is 2A7B-A245 Directory of d:\Program Files\Apache Software Foundation\Tomcat 9.0
This project is a prove-of-concept for the Apache Struts vulnerabilty. The goal was to create software that can generate and test random IPs for the vulnerabilty described above.
Use this project on your own risk and for educational purpose only.

## Results
it will automatically create a folder called results, and on each execution will create a dated folder containing the execution outcome. If threading is enabled, it will create on file per thread named thread_<number>, which can be ignored because when it completes it will consolidate all threads result on single TXT file with the same name (date/timestamp) as its execution folder.
