PayPal Payments Standard PHP Library before 20120427 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, related to intentional disabling of certificate-validation checks through a "FALSE" value.

Security readout for executives and security teams

This is a legacy PayPal PHP library issue where SSL certificate hostname checks were disabled. A person positioned between a site and PayPal could impersonate an SSL server using any otherwise valid certificate, undermining payment-related trust. Exposure is most likely in old PHP applications still using PayPal Payments Standard PHP Library before 20120427. The provided CVE data does not list CPEs, deployment patterns, or current supported versions. Prioritize review if the organization still runs legacy PHP payment code. The direct risk is payment-channel trust failure, but urgency is lower when no affected library is present and no exploitation evidence is cited. Mitigation focus: Inventory PHP payment integrations using PayPal Payments Standard PHP Library.; Upgrade any instance older than 20120427 or replace the legacy library.; Confirm SSL certificate validation and hostname verification are enabled..
