It doesn't account for database-specific syntax, but can allow for the process of switching databases and platforms to be fairly painless, simply by switching the connection string in many instances. PHP Object Injection is an application level vulnerability that could allow an attacker to perform different kinds of malicious attacks, such as Code Injection, SQL Injection, Path Traversal and Application Denial of Service, depending on the context.
