任意文件读取的深度利用

任意文件读取的利用思路
有些文件需要高权限才能读取

/etc/passwd # 用户情况
/etc/shadow # 直接 John the Ripper
/etc/hosts # 主机信息
/root/.bashrc # 环境变量
/root/.bash_history # 还有root外的其他用户
/root/.viminfo # vim 信息
/root/.ssh/id_rsa # 拿私钥直接ssh
/proc/xxxx/cmdline # 进程状态枚举 xxxx 可以为0000-9999 使用burpsuite
数据库 config 文件
web 日志 access.log, error.log
ssh 日志
/var/lib/php/sess_PHPSESSID # 非常规问题 session 文件( 参考 平安科技的一道session包含 http://www.jianshu.com/p/2c24ea34566b)

进一步推断系统版本

uname -a
lsb_release -d
cat /etc/issue
cat /proc/version
cat /etc/redhat-release 
cat /etc/debian_version
cat /etc/slackware_version
ls /etc/*version
cat /proc/cpuinfo

无痕反弹shell

kill -9 $$

常用默认路径整理
可以开虚拟机看看默认路径是什么

/root/.ssh/id_rsa.pub
/root/.ssh/authorized_keys
/etc/ssh/sshd_config
/var/log/secure
