Jscript加载Assembly踩坑记

从Jscript到C#
踩坑过程
问题解决
最后
@yzddmr6
最近想要给As-Exploits增加aspx类型的⽀持，就研究了⼀下冰蝎跟哥斯拉的实现。
由于冰蝎跟哥斯拉都采⽤的C#类型的shell，所以可以直接调⽤系统的⼀些api，并且可以加载任意的
shellcode。⽽蚁剑采⽤的是传统的Jscript。就想找个办法把它们两者结合起来，⽤Jscript加载C#的
assembly，以此来达到兼容原有shell类型的⽬的。
但是在实现的过程中踩了⼀些坑，所以就写下这篇⽂章记录⼀下。
这⾥要先提到⼀个概念叫Assembly，引⽤⼀下rebeyond师... | pdf |

安全认证相关漏洞挖掘

针对域证书服务的攻击（3）- ESC3
0x01 前言
在ESC1的利用的时候，好多小伙伴遇到一个错误，借用@Rcoil同学的图。解决方法也在星球，有@Rcoil
同学形成的文档。遇到这个错误的同学可以去看下。这个错误主要是因为2016以下的系统不支持这个
COM接口，因此需要改下代码。我开始以为是证书服务器16以下会出这个问题，但是我自己搭建12系统
的证书服务器环境发现并没有报错，因此我怀疑是域控在16以下。这算一个遗留问题，具体这个请求是
发送到域控还是证书服务器，需要后面分析，先mark下。

起因
昨天在微信群看到个链接
搜了下发现是铁威马的NAS，文章没写解密过程，今天闲来无事就分析了下
0x00 简析结构
铁威马的NAS系统的UI使用PHP开发且文件为加密状态，解压打开后发现加载了
php_terra_master.so 文件，丢到 IDA 里发现是魔改的 phpscrew 加密
网上找了几篇解密的文章发现都不成功，怀疑密钥被更改
0X01 找密钥
由于 phpscrew 魔改版会把 md5 加密后的秘钥的前16位写入被加密的文件，所以对历史版本的PHP文
件和新的文件进行对比，对比后发现密钥确实被修改
然后下载了历史版本 4.1.27 和 4.2.28 的版本，发现关键库文件被修改过

rc1的编译需要配置toolchains文件

关于昨天看到的url:的scheme
0x00 前⾔
昨天看到p
发出来的那个url:的scheme的⼩技巧感觉很有意思，就仔细看了⼀下。
⼤致如下：
意思是在url前加上前缀url:也可以正常执⾏，第⼀感觉应该是⽐如url:file:///etc/passwd可以拿来绕过startwith("file://")来请求file协议。
0x01 试⼀下
我不太懂java所以要试⼀下
正常请求百度，加了url：确实可以正常请求。试⼀下file
报错了，查了下，似乎是不允许把file协议丢给http handler来执⾏所以报错了。我不太清楚这是不是jdk1.8出来的问题。不过搜了⼀下改成下
⾯这样确实可以了

我一直是CS的忠实粉丝，随着CS4.4的发布，增加了反射DLL的自定义功能，让CS越来越高度可定制化
