“此伺服器已啟用 SSLv3 通訊協定，並且難以抵禦 Poodle (SSLv3) 攻擊。在伺服器上停用 SSLv3。"
2014 年，Google 的研究發現，SSL 3.0 通訊協定中的漏洞， 命名為 "POODLE" (Padding Oracle On Downgrading Legacy Encryption) 漏洞。
啟用 SSL 3.0 通訊協定時，MITM (man-in-the -middle) 可以攔截加密的連線，並計算所攔截連線的純文字。
SSL 3.0 漏洞/安全性瑕疵：
對付 POODLE 攻支的最有效方式是停用 SSL 3.0 通訊協定。
停用伺服器上的 SSL 3.0 通訊協定，啟用 TLS 1.2 或 1.3。
此外，DigiCert 建議停用 SSL 3.0 通訊協定，但啟用用戶端上的 TLS 通訊協定 (1.2 或 1.3)。
