Title: SSL/TLS协议加密算法RC4存在漏洞

Description:

SSL（Secure Sockets Layer，安全套接层）及TLS（Transport Layer Security，传输层安全）是为网络通信提供安全及数据完整性的一种安全协议。TLS与SSL在传输层对网络连接进行加密，是一个被广泛使用的加密协议。

SSL/TLS协议加密算法RC4存在漏洞。由于通过“受戒礼”攻击，攻击者可以在特定环境下只通过嗅探监听就可以还原采用RC4保护的加密信息中的纯文本，导致账户、密码、信用卡信息等重要敏感信息泄露，并且可以通过中间人攻击（Man-in-the-middle）进行会话劫持。

Severity: 高
