CVE-OLON-QLPQ
pkexec本身是⽤来授权⽤户以其他身份执⾏程序，他具备suid属性，但由于常规功能下不⽀持直接执⾏
命令，⽆法利⽤于suid提权。
pkexec是polkit （默认安装的系统服务）这个套件的程序。
CVE-2021-3560 利⽤的dbus-send，这次是 CVE-2021-4034 利⽤的 pkexec，上次影响的<=0.113
版本，这次影响全部版本。
Ubuntu、Debian、Fedora 和 CentOS 等默认安装pkexec，均受影响
暂时⽆吧

从服务创建拦截看端上主防软件的工作原理和
绕过方法
前言
书接上文，在上一篇中我们详细讲解了服务的工作原理和隐藏方法，但是如果我们的服务根本就无法直
接注册到系统中，那上一节的内容就是白扯。所以怎么能够绕过端上类似于360主动防御类型的软件，
将我们的服务注册进系统，是一个棘手的问题，我们本节就着重研究这个问题，看怎么绕过。
从端上主防软件的工作原理讲起
本文把在客户端上利用行为进行拦截的软件成为端上主防软件，简称为hips，360的主动防御模块就是
典型的端上主防软件。这类软件复杂的会有用户态监控和内态监控，例如crowdstrike的Falcon，简单的

大白话解释拟态安全
一、前言
一千个读者有一千个哈姆雷特，可能我有一些地方没有理解透彻和没有彻底明白，所以对于我讲的
东西存在偏面或者不好地方，欢迎指正但是不要骂我。
各位师傅可能这几年都听过一些特别高大上的词语，拟态安全，内生安全...在我看来，一开始，可能以
为这是什么全新的技术，全新的理念。其实都是一些旧概念，旧技术的衍生。我们今天主要来讲的就是
拟态安全，究竟是什么东西，尽量使用能听得懂的话语，来进行通俗易懂的解释。
此外，要注意的是，拟态安全并没有开源或公开的设备，或者说我这种菜鸡接触不到。所以我只能根据
网上的公开的文章，论文等资料进行阅读和理解，进行云解答。所以一定会存在理解误差的情况。我会

对 log4j2 漏洞的后续研究中，发现⼀些有趣的东⻄，记录分享⼀下
⾸先提出⼀个问题，log4j 真的在任何情况不存在 JNDI注⼊吗？
答案是否定的。
翻阅 Log4j2 的 pull request 发现⼀个有意思的对话：
有⼈提出实际上 log4j 和 log4j2 ⼀样易受攻击的，只不过与 log4j2 相⽐，Log4j 的攻击向量“更安全”
因为 Log4j 的攻击⼊⼝点是其配置⽂件，⽽ log4j2 的攻击⼊⼝点是⽤户的输⼊
那么实际上如何呢？经过我简单测试，发现修改 log4j 的配置⽂件确实会导致漏洞的产⽣，但要求要⽐pull
reques中所说的更苛刻。

1、概要
本文以如何劫持(窃取)智能家居时代设备的身份“安全凭证”为出发点，调研并分析了目
前国内市场的主流产品和设备交互协议，及其所依赖身份凭证，通过介绍、分析和发现设备
交互控制协议安全性，最终通过身份劫持，实现相关设备和产品的任意远程控制。
2、智能家居身份和劫持危害
先通过一张简图来了解一下应用、智能设备和云端三者交互时携带的身份标识，如图 2.1
所示：

从上图了解到，智能家居身份标识通常是以下几种情况：

HTTP认证方案
Author：h0ld1rs，Reclu3e
前言
因为HTTP协议是开放的，可以任人调用。所以，如果接口不希望被随意调用，就需要做访问权限的控
制，认证好的用户，才允许调用API。
本篇文章在郁离歌师傅的指导下，参考RFC对HTTP常用的认证方案做了归纳总结
Form认证
最常见的一种认证方式，即表单认证，表单认证一般都会配合cookie+sessiond的使用，现在绝大多数
的Web站点都是使用此认证方式。用户在登录页中填写用户名和密码，服务端认证通过后会将sessionId
返回给浏览器端，浏览器会保存sessionId到浏览器的Cookie中。因为Http是无状态的，所以浏览器使用

这https://t.zsxq.com/2R7mY3J中，有部门利用不够完善，在这儿补充下。
mimiktz利用
mimiktz的作者本杰明的更新速度是真的快，windows上的实时利用，基本不出3天就更新出来。闲话不
多说。当我们有了hash以后我们怎么提权呢。上次说了使用setntml或者changentml，这个mimiktz也
是有的，因此可以直接使用mimiktz（照顾新手同学，我想了想还是补充下）。
