CVE-2012-5794 in MoneyBookers
Summary
by MITRE
The MoneyBookers 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.

The vulnerability described in CVE-2012-5794 represents a critical SSL certificate validation flaw within the MoneyBookers payment module of the osCommerce e-commerce platform. This issue stems from improper SSL certificate verification mechanisms that fail to properly validate the server identity during secure communications. The vulnerability specifically affects the handling of X.509 certificates in the SSL/TLS handshake process, where the system does not adequately check whether the server hostname matches the domain name specified in the certificate's Common Name field or Subject Alternative Name extensions.
This security weakness creates a significant attack surface for man-in-the-middle adversaries who can exploit the flawed certificate validation to impersonate legitimate SSL servers. The vulnerability allows attackers to present arbitrary valid certificates that would normally be accepted by proper SSL implementations, thereby enabling them to intercept and potentially manipulate sensitive financial transactions between customers and the e-commerce platform. The flaw essentially undermines the fundamental security principle of certificate-based authentication that is essential for protecting sensitive data exchanges in online payment processing environments.
The operational impact of this vulnerability extends beyond simple data interception to encompass potential financial fraud and customer data compromise. When customers make payments through the affected osCommerce platform, their transaction details become vulnerable to eavesdropping and manipulation by attackers who can establish fraudulent SSL connections. This risk is particularly severe in payment processing contexts where sensitive financial information flows through the system, making the platform susceptible to credential theft, transaction manipulation, and unauthorized financial transfers.
From a cybersecurity perspective, this vulnerability aligns with CWE-295 which specifically addresses improper certificate validation and the failure to properly validate certificate hostnames. The attack vector corresponds to techniques documented in the ATT&CK framework under T1041 for data encryption for exfiltration and T1566 for credential harvesting through social engineering. Organizations implementing vulnerable versions of osCommerce should immediately address this issue through comprehensive security patches, certificate validation updates, and enhanced monitoring of SSL/TLS connections to prevent exploitation. The remediation process requires thorough verification of all SSL certificate validation mechanisms and implementation of proper hostname verification procedures to ensure that server identities are correctly authenticated during secure communications.
