Detailsinfo

A vulnerability has been found in CubeCart up to 6.6.x and classified as critical. Affected by this vulnerability is the function sqlSafe of the file admin.php?_g=orders&node=transactions of the component Admin Password Handler. The manipulation of the argument sort with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

CubeCart is an ecommerce software solution. Prior to 6.7.0, the admin orders-transactions listing page (admin.php?_g=orders&node=transactions) builds a raw ORDER BY SQL fragment from the attacker-controlled $_GET['sort'] array without column or direction validation. Both the column key and the direction value flow into the query string as bare SQL tokens, and the framework's sqlSafe() (mysqli escape_string) escapes only quote characters — none of which are required for ORDER BY injection. An authenticated administrator with the minimum CC_PERM_READ permission on orders can execute arbitrary SQL against the store database, including time-based blind extraction of admin password hashes, customer PII, and integrated payment-gateway credentials. This vulnerability is fixed in 6.7.0.
