# CVE-2024-0566 Smart Manager 8.27.0 - Post-Authenticated SQL Injection

**Exploit Title:** Smart Manager 8.27.0 - Post-Authenticated SQL Injection  
**Date:** 2024-01-18  
**Exploit Author:** Ivan Spiridonov - xbz0n  
**Vendor Homepage:** https://www.storeapps.org/    
**Software Link:** https://www.storeapps.org/product/smart-manager/  
**Version:** 8.27.0  
**Tested on:** Ubuntu 22.04  
**CVE:** CVE-2024-0566

## SQL Injection

The plugin does not properly sanitize and escape a parameter before using it in an SQL statement, leading to an SQL injection exploitable by high-privilege users such as admin.

## Affected Components

- **Plugin:** Smart Manager
- **Version:** 8.27.0
- **Affected Parameters:** 'sort_params%5BsortOrder%5D', 'sort_params%5Bcolumn%5D'
- **Affected Endpoint:** /wp-admin/admin-ajax.php

## Description

The vulnerability is located within the admin AJAX endpoint in the sorting parameters 'sort_params%5BsortOrder%5D' and 'sort_params%5Bcolumn%5D'. By manipulating these parameters, authenticated attackers can inject SQL commands, leading to a time-based SQL Injection vulnerability.

## Proof of Concept

```

If the server response is delayed by approximately 20 seconds, it indicates a successful exploitation of the time-based SQL Injection, confirming the vulnerability.

## Recommendations

Users of Smart Manager v8.27.0 are strongly advised to restrict access to the affected endpoint and update the plugin to the latest version.
