Accessing a SimpleDB database with a user-controlled item name and without proper access control can allow an attacker to view unauthorized records.
Database access control errors occur when:
1. Data enters a program from an untrusted source.
2. The data is used to specify the item name in a SimpleDB access call.
Example 1: The following code operates on a database of invoices named after the date of their transaction. The program first authenticates customers and subsequently lets them select from a list previous invoices.
...
String selectedInvoice = request.getParameter("invoiceDate");
...
AmazonSimpleDBClient sdbc = new AmazonSimpleDBClient(appAWSCredentials);
GetAttributesResult sdbResult = sdbc.getAttributes(new GetAttributesRequest("invoices", selectedInvoice));
