# About the Product:
B.A.S C2Box provides global solutions enabling full control and visibility over cash positions and managing domestic or cross border payment processes.
# Description:
This Cross-Site Request Forgery vulnerability enables an anonymous attacker to add an admin account into the application. This leads to compromising the whole domain as the application normally uses privileged domain account to perform administration tasks.
Also the attacker can reset any user's password after gaining the privileged account.
# Vulnerability Class:
Cross-Site Request Forgery (CSRF) - https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)
# How to Reproduce: (POC):
Host the attached code in a webserver. Then send the link to the application Admin. The admin should be logged in when he clicks on the link.
You can entice him to do that by using social engineering techniques.
Say for example: Log into the application and click the following link to get free licenses
