Following security controls should be implemented for File Upload functionality: If you use the Parameters collection, SQL treats the input is as a literal value rather then as executable code.The Parameters collection can be used to enforce type and length constraints on input data. If type-safe SQL parameters are not used, attackers might be able to execute injection attacks that are embedded in the unfiltered input.Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input.
