CVE-2012-5797: The PayPal Pro PayFlow module in osCommerce does not verify that the server hostname matches a domain name...

The PayPal Pro PayFlow module in osCommerce does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Security readout for executives and security teams

This vulnerability concerns osCommerce’s PayPal Pro PayFlow module failing to confirm that an SSL certificate belongs to the intended server. If an attacker can intercept traffic, they may impersonate the payment server with another valid certificate. The sources do not provide affected versions, CVSS, a named patch, or evidence of active exploitation. Exposure is most likely on legacy osCommerce deployments using the PayPal Pro PayFlow module. The source bundle does not identify exact affected versions, package names, or whether maintained deployments still include the vulnerable behavior. Treat this as a legacy payment-integration risk. It is not proven actively exploited in the supplied sources, but payment traffic interception can have serious confidentiality and fraud implications. Prioritize inventory and replacement or validation of any still-running osCommerce PayFlow integration. Mitigation focus: Inventory osCommerce sites and confirm whether PayPal Pro PayFlow is enabled.; Check osCommerce and PayPal module vendor guidance for an official fixed version.; Upgrade or replace the PayFlow module if vendor guidance identifies a maintained fix..
