your welcome.
Faveo helpdesk application is good software for helping ITSM Process. I feel happy if I can help test for new version Faveo.
Don't be hesitate to contact me ^_^
We are so happy to increase Faveo community! That is our vision too
I. Background: Faveo Helpdesk Open source ticketing system build on Laravel framework. Faveo word is derived from Latin which means to be favourable. Which truly highlights vision and the scope as well as the functionality of the product that Faveo is. It is specifically designed to cater the needs of startups and SME's empowering them with state of art, ticket based support system. In today's competitive startup scenario customer retention is one of the major challenges. Handling client query diligently is all the difference between retaining or losing a long lasting relationship.
II. Description: Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application.
Faveo have roles:
III. Exploit: CSRF Target is: “/public/rolechangeadmin/USER_ID”
user id = 11 (role is agent)
We have low privilege as “agent” to access application, and then want to change be admin role.
