漏洞描述
中文描述:
Cisco Web Security Appliance(WSA)是美国思科(Cisco)公司的一款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。AsyncOS Software是使用在其中的一套操作系统。 Cisco WSA中的AsyncOS Software的Web代理功能存在输入验证错误漏洞,该漏洞源于程序没有对通过受影响设备所发送的HTTP/HTTPS请求中的字段进行充分地输入验证。远程攻击者可通过发送恶意的HTTP/HTTPS请求利用该漏洞造成流量处理终止,导致拒绝服务。
英文描述:
A vulnerability in the web proxy functionality of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation mechanisms for certain fields in HTTP/HTTPS requests sent through an affected device. A successful attacker could exploit this vulnerability by sending a malicious HTTP/HTTPS request through an affected device. An exploit could allow the attacker to force the device to stop processing traffic, resulting in a DoS condition.
