1. Description:
This plugin keeps a record of a users IP & User-Agent history. The User-Agent isn't sanitized to user input allowing for an XSS via ACP.
2. Proof of Concept:
- Change your User-Agent to a payload <script>alert('XSS')</script>
- Log into an account
When admin visits the IP/User-Agent history page the payload will execute
http://localhost/[path]/admin/index.php?module=tools-ip_history_logs
3. Solution:
Update to 1.0.3
