Description:The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.

Readme

# check_struts

This project has been created following 2017 [Equifax exploit]( https://thehackernews.com/2017/09/equifax-apache-struts.html)

The **check_struts.sh** script aims at retrieving any Apache struts libraries version and location found and/or loaded on the system.
It can be run directly on a server, or with the provided Ansible playbook, to handle several servers.


## Possible Outputs:

- *"Libs path and versions loaded on the system:"*  

   The libraries found are currently running on the system, and could be accessible.

- *"Libs path and versions installed on the system:"* 

   The librairies are present on the filesystem, but not running.
   
 ## Example with Ansible Playbook:
 
 ```
 ➜  ansible-playbook git:(master) ✗ ansible-playbook play.yml -i inventory
