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.

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.

Unspecified vulnerabilities in Zen Cart before 1.2.7 allow remote attackers to cause unknown impact via unspecified vectors related to "other attempted exploits" other than SQL injection.

SQL injection vulnerability in Zen Cart before 1.2.7 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
