这里直接来到一个交易平台
还是三板斧
源码查看
<script>
$('#searchList li').click(function(){
var type=$(this).attr('aman-type');
$(this).parent().find('li').attr('class','red');
$(this).attr('class','red-on')
search();
});
function search(){
var url='/index';
var type=$("#type .red-on").attr('aman-value');
if(type!=''){
url+='/type/'+type;
}
location.href=url;
}
</script>
在源码中找到一个显露出来的script代码
响应报文查看
这里发现phpsessid，这点要注意
这里就是一个完整的网站架构，现在我们猜测flag的位置
这里有这几个跳转页面，一般来说首页没啥好测的
我们分别点开
二手
求购
公告
登录
注册
按照思路，先进行数据库渗透
公告页面首当其冲
我们查看后，发现规律
这里的页面并不是传参访问
而是直接跳转访问，所以不存在get的sql注入
先尝试下任意文件访问漏洞是否存在
这里出现个没有显示出来的页面
再然后就没有更多了
接下来就是商品页面
发现求购页面是假的，只有二手页面可以点开
发现这里访问页面传参，可以进行sql注入测试
在商品下发现评论，可以进行xss漏洞测试
先进行xss漏洞测试
要登录，先登录
随意注册了个账号，并登录
评论了两下，发现<>被注释
这种就是代表对方xss反渗透做的很好，没必要继续xss测试
接下来进行sql注入测试
这里看到闭合错误，说明这里有sql注入点
好家伙，居然对注释字符进行了过滤，无法闭合，sql注入点不存在
这下面有三个接口
因为求购页面是假的，所以先尝试发布二货
因为这里发布的填写数据，是可以被我们直接访问到的，如果我们在这些信息中包含一句话木马，是否可以利用菜刀或蚁剑连接呢
这里的二货和求购都在审核，相当离谱
相片和昵称都尝试上传一句话木马
这里可以看到，如果头像的一句话木马上传成功，则可以直接访问连接，成功getshell
上传正常图像抓包
但一旦上传非正常图像上去，就会出现加载不出来的情况
因为没有报文发送，应该是卡在html" title=前端>前端这个图像编辑器这里
这里在选中非正常图片的报文是这样的
正常图片的报文是这样的
这里会多出一个data报文
这里我们抓取上传报文，将这里的image数据给改了，改为一句话木马
显示上传失败
有可能是没有加密
把数据夹杂进去
提示保存成功
但是这里是jpeg文件，蚁剑只能连接php文件
所以要改后缀
多次提交后发现，不论提交的是什么后缀最后都会改为jpeg后缀
从上面探查到的报文和bp抓下来的报文进行分析
这里看到data这个关键字，即下面的是上面报文加密的状态
下面解密后得到
