The LinkPoint module in Zen Cart 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 Authorize.Net eCheck module in Zen Cart 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 PayPal Payments Pro module in Zen Cart 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 use of the PHP fsockopen function, a different vulnerability than CVE-2012-5805.

The PayPal IPN functionality in Zen Cart 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, a different vulnerability than CVE-2012-5806.

Cross-site scripting (XSS) vulnerability in zc_install/includes/modules/pages/database_setup/header_php.php in Zen Cart 1.5.0 and earlier, when the software is being installed, allows remote attackers to inject arbitrary web script or HTML via the db_username parameter to zc_install/index.php.

Cross-site scripting (XSS) vulnerability in includes/templates/template_default/templates/tpl_gv_send_default.php in Zen Cart before 1.5 allows remote attackers to inject arbitrary web script or HTML via the message parameter in a gv_send action to index.php, a different vulnerability than CVE-2011-4547.

The installation for Zen Cart stores sensitive information and insecure programs under the (1) docs, (2) extras, and (3) zc_install folders, and (4) install.txt, which allows remote attackers to obtain sensitive information, delete the database, and conduct other attacks via a direct request, different vulnerabilities than CVE-2009-4321 and CVE-2009-4322.

extras/ipn_test_return.php in Zen Cart allows remote attackers to obtain sensitive information via a direct request, which reveals the installation path in an error message.

Zen Cart 1.3.8a, 1.3.8, and earlier does not require administrative authentication for admin/record_company.php, which allows remote attackers to execute arbitrary code by uploading a .php file via the record_company_image parameter in conjunction with a PATH_INFO of password_forgotten.php, then accessing this file via a direct request to the file in images/.

Zen Cart 1.3.8a, 1.3.8, and earlier does not require administrative authentication for admin/sqlpatch.php, which allows remote attackers to execute arbitrary SQL commands via the query_string parameter in an execute action, in conjunction with a PATH_INFO of password_forgotten.php, related to a "SQL Execution" issue.

Zen Cart before 1.2.7 does not protect the admin/includes directory, which allows remote attackers to cause unknown impact via unspecified vectors, probably direct requests.

SQL injection vulnerability in admin/password_forgotten.php in Zen Cart 1.2.6d and earlier allows remote attackers to execute arbitrary SQL commands via the admin_email parameter.
