漏洞标题
Cisco Expressway系列和Cisco TelePresence VCS不正确证书验证漏洞
来源:AIGC 神龙大模型
漏洞描述信息
在Cisco Expressway-C和Cisco TelePresence VCS的证书验证中存在一个漏洞,该漏洞可能允许未经身份验证的远程攻击者非法访问敏感数据。漏洞是由于受影响设备在与Cisco Unified Communications Manager设备建立连接时,未能验证接收到的SSL服务器证书。攻击者可以利用中间人技术拦截设备间的通信,并使用自签名证书冒充终端。攻击成功后,攻击者可以以明文形式查看被拦截的流量或修改流量内容。 注意:Cisco Expressway-E不受此漏洞影响。Cisco已发布了修复此漏洞的软件更新。目前没有解决此漏洞的替代方法。

漏洞标题
Cisco Expressway Series and Cisco TelePresence VCS Improper Certificate Validation Vulnerability
来源:美国国家漏洞数据库 NVD
漏洞描述信息
A vulnerability in the certificate validation of Cisco Expressway-C and Cisco TelePresence VCS could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data.  The vulnerability is due to a lack of validation of the SSL server certificate that an affected device receives when it establishes a connection to a Cisco Unified Communications Manager device. An attacker could exploit this vulnerability by using a man-in-the-middle technique to intercept the traffic between the devices, and then using a self-signed certificate to impersonate the endpoint. A successful exploit could allow the attacker to view the intercepted traffic in clear text or alter the contents of the traffic. Note: Cisco Expressway-E is not affected by this vulnerability.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
