*inux 提权资料收集

指南概述

这只是一个粗略的基本指南。 由于Linux系统版本间差别非常大，并不是每个命令都适用于每个系统。
枚举是关键！
（Linux）的提权是怎么一回事：
收集–枚举，枚举和一些更多的枚举。
过程–通过数据排序，分析和确定优先次序。
搜索–知道搜索什么和在哪里可以找到漏洞代码。
适应–自定义的漏洞，所以它适合。每个系统的工作并不是每一个漏洞“都固定不变”。
尝试–做好准备,试验和错误。

find / -perm -u=s -type f 2>/dev/null # SUID (chmod 4000) - run as the owner, not the user who started it.
find / -perm -g=s -o -perm -u=s -type f 2>/dev/null # SGID or SUID
for i in `locate -r “bin$”`; do find $i ( -perm -4000 -o -perm -2000 ) -type f 2>/dev/null; done # Looks in ‘common’ places: /bin, /sbin, /usr/bin, /usr/sbin, /usr/local/bin, /usr/local/sbin and any other *bin, for SGID or SUID (Quicker search)
# find starting at root (/), SGID or SUID, not Symbolic links, only 3 folders deep, list with more detail and hide any errors (e.g. permission denied)
find / -perm -g=s -o -perm -4000 ! -type l -maxdepth 3 -exec ls -ld {} \; 2>/dev/null

在哪些目录可以写入和执行呢？几个通用的目录：/ tmp目录，/var / tmp目录/ dev /shm目录

find / -writable -type d 2>/dev/null # world-writeable folders
find / -perm -222 -type d 2>/dev/null # world-writeable folders
find / -perm -o w -type d 2>/dev/null # world-writeable folders
find / -perm -o x -type d 2>/dev/null # world-executable folders
find / ( -perm -o w -perm -o x ) -type d 2>/dev/null # world-writeable & executable folders

Any “problem” files？可写的，“没有使用”的文件

###缓解措施

上述任何信息是否容易找到？

使用第三方自动化脚本/工具试试吧！

系统是否完全修补？
系统内核，操作系统，所有应用程序，插件和Web服务是否安装最新补丁？

apt-get update && apt-get upgrade
yum update

服务是否以最低级别的特权运行？

例如，你需要以root身份运行MySQL吗？

能够从以下网站找到自动运行的脚本？！
