Hi, I am glad to release SFX-SQLi (Select For XML SQL injection), a new SQL injection technique which allows to extract the whole information of a Microsoft SQL Server 2005/2008 database in an extremely fast and efficient way. This technique is based on the FOR XML clause, which is able to convert the content of a table into a single string, so its contents could be appended to some field injecting a subquery into a vulnerable input of a web application. In most cases, this method can dump all the contents of any table using only ONE REQUEST to the web server, without the need of any special permission on the DBMS. I have written a paper describing how the technique works and in which fundamentals it is based, and I have also developed a tool which implements this technique as a proof of concept (with the source code included).
