Name SQL Injection through SOAP Parameter Tampering
Summary An attacker modifies the parameters of the SOAP message that is sent from the service consumer to the service provider to initiate a SQL injection attack. On the service provider side, the SOAP message is parsed and parameters are not properly validated before being used to access a database in a way that does not use parameter binding, thus enabling the attacker to control the structure of the executed SQL query. This pattern describes a SQL injection attack with the delivery mechanism being a SOAP message.
Prerequisites SOAP messages are used as a communication mechanism in the system SOAP parameters are not properly validated at the service provider The service provider does not properly utilize parameter binding when building SQL queries
Solutions Properly validate and sanitize/reject user input at the service provider. Ensure that prepared statements or other mechanism that enables parameter binding is used when accessing the database in a way that would prevent the attackers' supplied data from controlling the structure of the executed query. At the database level, ensure that the database user used by the application in a particular context has the minimum needed privileges to the database that are needed to perform the operation. When possible, run queries against pre-generated views rather than the tables directly.
