SQL injection vulnerability in OpenCart 1.1.8 allows remote attackers to execute arbitrary SQL commands via the order parameter.

Directory traversal vulnerability in index.php in OpenCart 1.1.8 allows remote attackers to read arbitrary files via a .. (dot dot) in the route parameter.

SQL injection vulnerability in index.php in OpenCart 1.3.2 allows remote attackers to execute arbitrary SQL commands via the page parameter.

Cross-site request forgery (CSRF) vulnerability in index.php in OpenCart 1.4 allows remote attackers to hijack the authentication of an application administrator for requests that create an administrative account via a POST request with the route parameter set to "user/user/insert." NOTE: some of these details are obtained from third party information.

OpenCart 1.4.9.3 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by system/startup.php and certain other files.

The Cart::getProducts method in system/library/cart.php in OpenCart 1.5.6.4 and earlier allows remote attackers to conduct server-side request forgery (SSRF) attacks or possibly conduct XML External Entity (XXE) attacks and execute arbitrary code via a crafted serialized PHP object, related to the quantity parameter in an update request.

Cross-site scripting (XSS) vulnerability in OpenCart before 2.1.0.2 allows remote attackers to inject arbitrary web script or HTML via the zone_id parameter to index.php.

SQL injection vulnerability in the updateAmazonOrderTracking function in upload/admin/model/openbay/amazon.php in OpenCart before version 2.3.0.0 allows remote authenticated administrators to execute arbitrary SQL commands via a carrier (aka courier_id) parameter to openbay.php.

The "program extension upload" feature in OpenCart through 3.0.2.0 has a six-step process (upload, install, unzip, move, xml, remove) that allows attackers to execute arbitrary code if the remove step is skipped, because the attacker can discover a secret temporary directory name (containing 10 random digits) via a directory traversal attack involving language_info['code'].

OpenCart through 3.0.2.0 allows directory traversal in the editDownload function in admin\model\catalog\download.php via admin/index.php?route=catalog/download/edit, related to the download_id. For example, an attacker can download ../../config.php.

/upload/catalog/controller/account/password.php in OpenCart through 3.0.2.0 has CSRF via the index.php?route=account/password URI to change a user's password.
