CVE-2012-5797: Input Validation
First published: Sun Nov 04 2012(Updated: )
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.
