This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active
Server Pages environment, but most of the techniques discussed have equivalents in other
database environments. It should be viewed as a "follow up", or perhaps an appendix, to
the previous paper, "Advanced SQL Injection".
The paper covers in more detail some of the points described in its predecessor, providing
examples to clarify areas where the previous paper was perhaps unclear. An effective
method for privilege escalation is described that makes use of the openrowset function to
scan a network. A novel method for extracting information in the absence of helpful
error messages is described the use of time delays as a transmission channel. Finally, a
number of miscellaneous observations and useful hints are provided, collated from
responses to the original paper, and various conversations around the subject of SQL
injection in a SQL Server environment.
本課程設計介紹了一個基于Client/Server模式的商品銷售管理系統的設計與實現。運用Visual Basic.Net結合Microsoft SQL Server 2000開發的登錄模塊主要用于驗證用戶身份，以及根據用戶類型授予相應權限進行有效的操作。從主界面模塊在驗證后進入每個子模塊進行各個子系統的具體功能操作。在整個系統設計中充分利用了模塊化的設計思想和開發方法。
