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.

Multiple cross-site scripting (XSS) vulnerabilities in Zen Cart 1.3.5 allow remote attackers to inject arbitrary web script or HTML via the (1) admin_name or (2) admin_pass parameter in (a) admin/login.php, or the (3) admin_email parameter in (b) admin/password_forgotten.php.

Directory traversal vulnerability in Zen Cart 1.3.0.2 and earlier allows remote attackers to include and possibly execute arbitrary local files via directory traversal sequences in the typefilter parameter.

index.php in Zen Cart 1.3.0.2 allows remote attackers to obtain sensitive information via empty (1) _GET[], (2) _SESSION[], (3) _POST[], (4) _COOKIE[], or (5) _SESSION[] array parameters, which reveals the installation path in an error message. NOTE: this issue might be resultant from a global overwrite vulnerability.
