把前4个月(HW — 现在)的笔记捋一捋、总结归档，也算是为这一年多的实习生活画

零、前⾔
⼗⼀本来打算不卷了，好好放松放松，但是⼏个事情对我触动⽐较⼤，所以就⼜给⾃⼰设了个搞懂 RMI 反序列化相
关攻击的学习⽬标。
再加上⼀是为后续深⼊ IIOP/T3 打下基础，⼆是最近⼀位师傅问了我关于利⽤ RMI 回显的思路，帮师傅搞了半天没
有搞定，怪我之前对 RMI 只是浅浅的了解，甚⾄都算不上会，没能帮上这位师傅的忙，很是⾃责，所以花点时间学
⼀学。
这部分的实现略有复杂，本⽂在写的时候也是深感吃⼒，RMI 相关的⽂章在⽹上乱七⼋糟，由于⼜涉及到安全更新
和绕过，之前看了⼏次看的头晕眼花，这次趁着有空梳理⼀下。

前言
周六晚上，本来打开电影网站准备看电影的时候，导师发来张图，说这个 exe 在添加进启动项的时候，
360没有拦截，就想着我们能不能也利用下。
先说结论：分析后我个人感觉利用难度较大，价值不高，如果有师傅可以成功利用的话，请疯狂call
我！！！
首先我的第一反应是白加黑，但很快被当头一棒，不能想当然。还是要老老实实分析，切忌主观臆断。
先了解下这个程序，看到这里喜忧参半，看描述似乎确实有木马伪装成这个程序，但这个程序有签名。
下面要做的就是分析这个程序的加载方式了，这里我选择的火绒剑来监控。
首先删除这个注册表项，然后重装vmtools，安装完成后， vmtoolsd.exe 会被写进启动项。我们做的

bof⼩测
⼀个正常C程序，如何转换成bof⽂件，这⾥记录下过程
bof的原理实现就不多讲了，简单来说就是编译成⼀个object⽂件（COFF格式，exe是PE格式），然后
传输给beacon后在终端上完成链接过程，这也就导致bof⽂件⾮常⼩，⼀般只有⼏K。
参考
https://wbglil.gitbook.io/cobalt-strike/cobalt-strike-yuan-li-jie-shao/untitled-3
在github有⼏个不错的开源项⽬，可以以此为模板进⼀步开发，⽽不需要完全重头开始。

0x01 前奏
前不久在挖掘某SRC时提交漏洞时，偶然在该SRC官⽹的编辑器发现了⼀个接⼝。
起初以为是任意⽂件包含能RCE了，后来测试发现只是拼接读取了远程资源站的图⽚，原本都想着放弃了，但是当
我在后缀添加了个+号后图⽚被意外的解析成了HTML⻚⾯，这不就意味着get到⼀个存储型XSS？
https://xxx.cn/xxxx/ueditor?image_name=/xxx.png+
接着测试发现拼接图⽚在⼀个⼆级⽬录下，尝试穿越发现存在⾃研WAF，于是Fuzz了下Payload成功Bypass。

HVV 之不需要密码永久退出 LM 天擎
1. 又要到护网了,还记得去年护网客户问我天擎退出密码是多少,说想安装软件
安装不上去。
2. 我心想,好家伙,这谁家的软件这么流氓。
3. 不需要逆向这么麻烦的方法，其实很简单，重启之后进入安全模式，这个时
候天擎是没有启动的。
4. 然后进入天擎的安装目录,这个时候天擎的安装目录名称是 Tianqing
5. 然后把目录修改成 Tianqing6666
6. 最后重启进入正常模式,因为目录名字变了,天擎的自启动也就失效了.
7. 如果后面用到的时候手动启动 TQSafeUI.exe 就可以了 | pdf |

PetitPotam配合基于资源委派的横向技巧
原理：使用PetitPotam将目标主机的身份认证中继到dc的ldap服务配置资源委派，然后使用资源
委派获取目标主机权限。
当微软修复CVE-2019-1040的时候，顺便修了smb中继到ldap。
但是我们还能通过http中继到ldap，但前提条件是目标打开Webclient服务，server默认不安装，
win7，win10默认安装但是需要手动打开服务。
条件：
域账户一个
目标主机需要打开Webclient服务
细节：
PetitPotam可以发起http请求，然后将http中继到ldap
http中继需要使用可信域名，域内dns即为可信域名

S-hessian反序列化
介绍
自己不会查吗?
这里有一个点就是Hessian的序列化与反序列化与原生序列化与反序列化不同，就以使用的Resin链而言，其中的ja
vax.naming.spi.ContinuationDirContext类并没有实现java.io.Serializable接口，但是hessian还是可以
正常对他进行序列化，用原生的序列化方式就会失败。区别就在于序列化对象时的一个设置，可以让未继承java.i
o.Serializable接口的类进行序列化。
使用
hessian的使用有很多场景，也结合了 servlet和 spring，这里的使用先使用自行封装，然后调试分析漏洞成因，
最后再看整合后的集中情况。... | pdf |
