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.

PHP remote file inclusion vulnerability in index.php in Zen Cart 1.3.0.2 and earlier, when register_globals is enabled, allows remote attackers to execute arbitrary PHP code via a URL in the autoLoadConfig[999][0][loadFile] parameter.

Multiple SQL injection vulnerabilities in Zen Cart 1.3.0.2 and earlier allow remote attackers to execute arbitrary SQL commands via (1) GPC data to the ipn_get_stored_session function in ipn_main_handler.php, which can be leveraged to modify elements of $_SESSION; and allow remote authenticated users to execute arbitrary SQL commands via (2) a session id within a cookie to whos_online_session_recreate, (3) the quantity field to the add_cart function, (4) an id[] parameter when adding an item to a shopping cart, or (5) a redemption code when checking out (dc_redeem_code parameter to includes/modules/order_total/ot_coupon.php).

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.

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.

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.

Zen Cart 1.2.6d and earlier, under certain PHP configurations, allows remote attackers to obtain sensitive information via direct requests to files in the admin/includes directory, including (1) graphs/banner_daily.php, (2) graphs/banner_infobox.php, (3) graphs/banner_yearly.php, (4) graphs/banner_monthly.php, (5) application_bottom.php, (6) attributes_preview.php, (7) modules/category_product_listing.php, (8) modules/copy_to_confirm.php, (9) modules/delete_product_confirm.php, and (10) modules/move_product_confirm.php, which leaks the web server path in the resulting error message.

The distribution of Zen Cart 1.1.4 before patch 2 includes certain debugging code in the Admin password retrieval functionality, which allows attackers to gain administrative privileges via password_forgotten.php.
