漏扫常见(可验证)漏洞复现方法

SSL/TLS协议信息泄露漏洞(CVE-2016-2183)

检测到目标服务支持SSL弱加密算法
检测到目标服务支持SSL中等强度加密算法

nmap -sV -p 端口 --script ssl-enum-ciphers 目标ip

缓慢的HTTP拒绝服务攻击

slowhttptest -c 65500 -B -i 10 -r 200 -s 8192 -t SLOWBODY -u https://xxxxxx

在这里插入图片描述
当显示为NO,则表示存在HTTP慢速攻击漏洞,可导致拒绝服务。

SSH支持弱加密算法

nmap -sV -p 端口 --script ssh2-enum-algos 目标ip

Apache Tomcat示例脚本信息泄露漏洞

访问其端口即可

http://目标ip:端口

Apache Tomcat文件包含漏洞
