Evolve Shopping Cart is prone to an SQL-injection vulnerability because the application fails to properly sanitize user-supplied input before using it in an SQL query. 

A successful exploit could allow an attacker to compromise the application, access or modify data, or exploit vulnerabilities in the underlying database implementation.

UPDATE: The vendor indicates that the application is not vulnerable to this issue.
