CVE: CVE-2017-15578, CVE-2017-15579

## Vulnerabilities details

Stored PreAuth XSS that leads to administrator account takeover
User controlled input is not sufficiently sanitized, such that by sending a POST request to page_manager.php with the following parameters (vulnerable parameter – page_title)


```
page_manager.php?do=new&id=&author=&showinmenu=0&meta_keywords=555-555-0199@example.com&status=0&submit=Publish&page_name=Peter+Winter&page_title=408b7<script>alert(1)<%2fscript>f2faf
```

An attacker can trigger the vulnerability and when administrator/moderator/editor or anyone with privileges visits Admin access /admin/pages.php?page=1 the payload is triggered and the alert is executed.


SQL Injection (1)
User controlled input is not sufficiently sanitized, by sending a POST request to /phpmelody/admin/edit_category.php with the following parameters:


```
category=3&meta_keywords=555-555-0199@example.com&tag=categoryone&save=Save$name=Sample+Category+%231&image='&meta_title=555-555-0199@example.com
```

The vulnerable parameter is the POST “image” parameter. We can send a single quote (‘) to verify and the server will respond with an SQL error. We can inject SQL Queries here or extract data.

This attack requires an admin/modernator or editor to visit a malicious website that will submit the form with a malicious “image” parameter as an Injection


SQL Injection (2)
SQL Injection is on a cookie-value and can be exploited without any user interaction.

The cookie value “aa_pages_per_page” is the vulnerable parameter and we can use time based SQL Injection techniques to verify,

The payload we used ‘ AND benchmark(20000000%2csha1(1))—makes the server sleep for a long time (5-20 seconds).
