Amazon SimpleDB queries should not be constructed using unvalidated external data.

Bad Practice

Avoid directly performing string concatenation to create SQL queries, as this can lead to injection attacks.

String table = request.getParameter("model");

String query = "SELECT * FROM " + table + " WHERE id = '" + id + "'"; // Susceptible to injection!
SelectResult result = SelectRequest(query));


In security, allow-lists are more preferable to deny-lists, due to how specific they can be. If possible, narrow down to the absolute minimum the behaviors that are desired within a query, and use external input only to select the behavior required for the specific purpose.

Make sure to sanitize data from files or requests by first passing it through allow-lists.

if (!allowlist.contains(table)) return;

// ...

String query = String.format("SELECT * from %s where id = '%s'", table, id);
