Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache HTTP Server（由 Apache 软件基金会开发）在 2.4.68 及更早版本中，mod_proxy_ftp 模块对 FTP PASV（被动模式）响应地址的验证不当。在所有平台上，若配置为正向代理，攻击者可利用一个不可信的 FTP 服务器通过构造恶意的 PASV 响应，诱导代理向任意第三方主机发起数据连接。 建议用户升级至 2.4.69 版本，该版本已修复此问题。
