This paper will present a new class of attack, called SQL Smuggling. SQL Smuggling is a sub-class of SQL Injection attacks that rely on differences between contextual interpretation performed by the application platform and the database server. While numerous instances of SQL Smuggling are commonly known, it has yet to be examined as a discrete class of attacks, with a common root cause. The root cause in fact has not yet been thoroughly investigated; this research is a result of a new smuggling technique, presented in this paper. It is fair to assume that further study of this commonality will likely lead to additional findings in this area.
