中文标题:
多款Cisco产品AsyncOS输入验证错误漏洞
英文标题:
Cisco ESA, Cisco WSA, and Cisco SMA GUI Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Content Security Management Appliance（SMA）等都是美国思科（Cisco）公司的产品。Cisco Content Security Management Appliance是一套内容安全管理设备。该设备主要用于管理电子邮件和Web安全设备的所有策略、报告、审计信息等。AsyncOS Software是运行在其中的一套操作系统。Cisco Email Security Appliance是一个电子邮件安全设备。Cisco Web Security Appliance是一款Web安全设备。该设备提供基于SaaS的访问控制、实时网络报告和追踪、制定安全策略等功能。 多款Cisco产品中的AsyncOS的Web管理接口存在输入验证错误漏洞，该漏洞源于没有正确验证HTTP请求报头。远程攻击者可通过发送格式错误的HTTP请求利用该漏洞占用大量CPU，导致拒绝服务。以下产品及版本受到影响：Cisco ESA 13.0.0-392及之前版本（Release）；Cisco Cloud Email Security 13.0.0-392及之前版本（Release）；Cisco WSA 12.0.1-268及之前版本（Release）；Cisco SMA 13.6.0及之前版本（Release）。
英文描述:
A vulnerability in the web-based management interface of Cisco AsyncOS for Cisco Email Security Appliance (ESA), Cisco Web Security Appliance (WSA), and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of specific HTTP request headers. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to trigger a prolonged status of high CPU utilization relative to the GUI process(es). Upon successful exploitation of this vulnerability, an affected device will still be operative, but its response time and overall performance may be degraded.
