Multiple SQL injection vulnerabilities in AlegroCart 1.2.8 allow remote administrators to execute arbitrary SQL commands via the download parameter in the (1) check_download and possibly (2) check_filename function in upload/admin2/model/products/model_admin_download.php or remote authenticated users with a valid Paypal transaction token to execute arbitrary SQL commands via the ref parameter in the (3) orderUpdate function in upload/catalog/extension/payment/paypal.php.

PHP remote file inclusion vulnerability in the get_file function in upload/admin2/controller/report_logs.php in AlegroCart 1.2.8 allows remote administrators to execute arbitrary PHP code via a URL in the file_path parameter to upload/admin2.

Cross-site request forgery (CSRF) vulnerability in AlegroCart 1.1 allows remote attackers to hijack the authentication of the administrator for requests that reset the administrator password via a POST to admin/ with an update action.

AlegroCart 1.2.3 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 common.php and certain other files.
