CVE-2012-5807: The Authorize.Net eCheck module in Zen Cart does not verify that the server hostname matches a domain name...

Security readout for executives and security teams

Zen Cart's Authorize.Net eCheck module is reported to accept SSL certificates without confirming they belong to the intended server. In a payment workflow, that can let an attacker positioned on the network impersonate the payment endpoint and intercept or alter sensitive traffic. The supplied sources do not provide affected versions or a vendor fix. Likely exposure is Zen Cart stores using the Authorize.Net eCheck module for payment processing. The source bundle does not identify affected versions, default configurations, or whether other Zen Cart payment modules are involved. Prioritize review if the organization still runs Zen Cart with Authorize.Net eCheck, especially on revenue-generating stores. Payment interception risk is business-relevant, but urgency is tempered by missing version data and no cited active exploitation. Mitigation focus: Inventory Zen Cart deployments using the Authorize.Net eCheck module.; Check Zen Cart and Authorize.Net module guidance for supported fixes or replacements.; Disable the eCheck module if no supported remediation is available..
