Turning Blind Error Based MSSQL Injection into Exploitable Boolean One

Turning Blind Error Based SQL Injection Into An Exploitable Boolean One

Where a Microsoft SQL Server injection point returns no error text, the application differing redirect targets still reveal whether a query succeeded. Wrapping the IIF function inside a convert to char, so a true branch yields a convertible integer and a false branch yields a value that fails conversion, turns each guess into one bit and extracts data character by character.
