upload-labs刷关记录

闲来无聊，把upload-labs所有的关卡都刷一遍，就当复习一下文件上传漏洞的各种绕过技巧吧，做完一关再看看源代码提高一下审计能力挺好的

Pass-01

一个前端检测，可以禁用js，也可以直接抓包就可以绕过上传

访问成功

Pass-02

Content-Type绕过，直接把Content-Type改为图片类型即可

上传成功

Pass-03

这一关是另类的文件名的绕过，可以尝试phtml，php3，php4, php5, pht后缀名都可以绕过，但是前提是要在配置文件里面有这样的一句话

AddType application/x-httpd-php .php .phtml .phps .php5 .pht

成功回显

源码里面直接用的黑名单。。

$deny_ext = array('.asp','.aspx','.php','.jsp');

当然还有第二种方法

就是上传.htaccess，实现重写文件解析,同样这样的前提也是得在配置文件里面有这样的一句话

AllowOverride All
LoadModule rewrite_module modules/mod_rewrite.so

Pass-04

上面的方法已经不行了，可以看一下他过滤的名单

$deny_ext = array(".php",".php5",".php4",".php3",".php2","php1",".html",".htm",".phtml",".pht",".pHp",".pHp5",".pHp4",".pHp3",".pHp2","pHp1",".Html",".Htm",".pHtml",".jsp",".jspa",".jspx",".jsw",".jsv",".jspf",".jtml",".jSp",".jSpx",".jSpa",".jSw",".jSv",".jSpf",".jHtml",".asp",".aspx",".asa",".asax",".ascx",".ashx",".asmx",".cer",".aSp",".aSpx",".aSa",".aSax",
