Title

Cisco Web Security Appliance拒绝服务漏洞（CNVD-2015-07874）

Description

Cisco Web Security Appliance是安全的Web网关，在一个平台上集成了恶意软件防护、应用可视化控制、策略控制等。 Cisco Web Security Appliance (WSA)设备（8.0.7-142及8.5.1-021软件版本），passthrough FTP功能存在安全漏洞，未经身份验证的远程攻击者通过WSA启动FTP连接后，利用此漏洞可造成较高的CPU利用率，导致拒绝服务。当FTP客户端在数据转移完成时中断FTP控制连接会触发此漏洞。
