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HTTPS解密功能存在输入验证错误漏洞,该漏洞源于程序没有充分地验证SSL服务器的证书。远程攻击者可通过安装畸形的证书利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the HTTPS decryption feature of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Secure Sockets Layer (SSL) server certificates. An attacker could exploit this vulnerability by installing a malformed certificate in a web server and sending a request to it through the Cisco WSA. A successful exploit could allow the attacker to cause an unexpected restart of the proxy process on an affected device.
