 * @description
 * CWE: 89 SQL Injection
 * BadSource: connect_tcp Read data using an outbound tcp connection
 * GoodSource: A hardcoded string
 * Sinks: executeQuery
 *    GoodSink: Use prepared statement and executeQuery (properly)
 *    BadSink : data concatenated into SQL statement used in executeQuery(), which could result in SQL Injection
 * Flow Variant: 81 Data flow: data passed in a parameter to an abstract method
