pass-01

bash
本pass在客户端使用js对不合法图片进行检查！

前端绕过, 禁用前端js代码, 或者上传图片, 抓包改后缀为 ` php` , 后端没有校验

pass-02

bash
本pass在服务端对数据包的MIME进行检查！

后端绕过, 需要文件类型绕过, 只允许图片的文件类型上传, 直接上传一句话木马的 php 文件, 后端改下文件类型就可以绕过也可以直接写个 php 木马, 修改后缀上传

pass-03

bash
本pass禁止上传.asp|.aspx|.php|.jsp后缀文件！

后端校验, 黑名单, 过滤一些后缀的文件上传, 正常来说上传一些 ` .php3`` .php5` 之类的是可以的

pass-04

bash
本pass禁止上传.php|.php5|.php4|.php3|.php2|php1|.html|.htm|.phtml|.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|.aScx|.aShx|.aSmx|.cEr|.sWf|.swf后缀文件！

后端校验, 黑名单, 较上一关, 能过滤的都过滤了, 只有 ` .htaccess` 没有过滤, 我们上传一个该文件, 用于允许该服务器解析某种后缀的文件, 随便上传个东西, 抓包修改, 文件名改为 ` .htaccess` , 内容为 ` AddType application/x-httpd-php .jpg` , 然后再上传一个文件名为 ` .jpg` , 内容为一句话木马, 就可以上传成功, 配置文件 ` httpd.conf` 里面的该内容要改为 ` AllowOverride all` 才可以写 ` .htaccess` 文件

上传的配置文件

pass-05

使用 ` . .` 绕过, 线上的环境没有成功, 没办法

bash
上传目录存在php文件（readme.php）

这关过滤了绝大多数的后缀, 但是可以通过 .  或 . . 绕过, wp 是可以, 但我怎么都不解析

这一关使用的是大小写绕过

这一关是留空, php 后面加个空格就可以绕过, 一样, 环境问题, 没有成功

和第七关一样, 没有删除文件名末尾的点, 空格换成 ` .` , 可以绕过, 环境导致没有上传成功

bash
本pass上传路径可控！

白名单, get 请求允许哪些文件可以上传, 这边使用 %00 , 也就是 00 截断来绕过, 有个条件就是 php 版本需要低于 5.3 且 magic_quotes_gpc 关闭, 最后, 这个线上环境上传依然不成功

上传的文件名不用改, 添加下 get 请求的文件名为 ma1.php%00 [[HOME/Secure/靶场/upload-labs/files/b95666c836a4472eb19c7a552af3954e_MD5.jpeg|Open: Pasted image 20241115230910.png]] ![](https://i-blog.csdnimg.cn/img_convert/f274c5088f8bb0f6db629feef133e5d4.jpeg)

pass-13

bash
本pass上传路径可控！

白名单, 使用了 POST 请求, 使用 POST 请求 00 截断, 途中框住的浅蓝色的是 %00 url编码过后的内容
[[HOME/Secure/靶场/upload-labs/files/f17a5b5e94cfac52e89f5a6eac77d55a_MD5.jpeg|Open: Pasted image 20241115232643.png]]

pass-14

bash
本pass检查图标内容开头2个字节！

访问 url/include.php 就可以看到文件包含的代码

bash
<?php  
/  
本页面存在文件包含漏洞，用于测试图片马是否能正常运行！  
/  
header("Content-Type:text/html;charset=utf-8");  
$file = $_GET['file'];  
if(isset($file)){  include $file;  
}else{    show_source(__file__);  
}  
?>

使用 cmd 写一个图片马

bash
copy m.png/b + m.txt/a ma.png

然后上传, 这个可以成功, 访问 ` url/include?file=upload/3020241115153340.jpg` , 然后 POST 请求填写 ` cmd=system('ls');` 可以执行命令 [[HOME/Secure/靶场/upload-labs/files/60801a51edab75861a6d6a6580687830_MD5.jpeg|Open: Pasted image 20241115234748.png]] ![](https://i-blog.csdnimg.cn/img_convert/999f0448f11521acc7686cc6bd221f3f.jpeg)

pass-15

bash
本pass使用getimagesize()检查是否为图片文件！

该函数用于检查上传的文件是否为图片, 所以和上一关一样, 直接上传个图片马, 可以直接文件包含来进行命令执行

pass-16

bash
本pass使用exif_imagetype()检查是否为图片文件！

这一关也是和上面的两关类似, exif_imagetype() 读取一个图像的第一个字节并检查其签名

pass-17

bash
本pass重新渲染了图片！

这关卡有二次渲染函数, 渲染成功会返回图像标识符或图像资源, 失败返回 false , 会导致图片马数据丢失, 上传自然失败

把原图和他修改过的图片进行比较，看看哪个部分没有被修改。将php代码放到没有被更改的部分，配合包含漏洞，就可以了。
具体实现需要自己编写Python程序，人工尝试基本是不可能构造出能绕过渲染函数的图片webshell的，知道怎么解就可以了。

这句话是 wp 的, 因为需要写脚本, 我没有实现出来

pass-18

bash
需要代码审计！

需要条件竞争, 源码大概就是先上传图片, 才开始判断后缀名, 然后二次渲染, 如果我们在上传文件之后在他删除之前立刻访问, 那么他就无法删除了, 因为已经被访问的文件无法被删除, 可以使用 bp 的爆破来让他一直发送上传请求, 然后挂在那, 换个浏览器一直访问包含该木马的 url , 从而达到条件竞争

这边我使用了前几关一样的上传图片马, 然后文件包含, 就可以命令执行

pass-19

bash
需要代码审计！

他的 wp 说的是

这关是检查了后缀名，然后上传，然后在进行二次渲染。这时我们只能上传图片马，而且得配合解析漏洞进行通关

操作和18关的一样，就是访问地址是加上包含漏洞的。

这一关我也是直接传个图片马, 直接可以拿到命令执行权限, 他这个上传成功的路径就是这个 up1oad1731687882.png , 访问

pass-20

bash
本pass的取文件名通过$_POST来获取。

他这个上传成功的路径也就是这个 upload-19.jpg , 访问后显示

[[HOME/Secure/靶场/upload-labs/files/d2b28d9eb5a8346a2de6e88ee3a0931f_MD5.jpeg|Open: Pasted image 20241116003037.png]]

pass-21

bash
Pass-20来源于CTF，请审计代码！

他的 wp :
十九关是一个黑名单，php/.就可以绕过，但是二十关他会检测文件后缀名，是一个白名单。所以把他拆分掉第三部分是.png，所以就会上传。实际上他上传上去的东西是
upload-21.php/.png 上传上去的东西就是upload-21.php。实现了绕过。

我没有复现出来

图片马依然可以绕过
