漏洞描述
中文描述:
Cisco Expressway Series是美国思科（Cisco）公司的一款用于防火墙外访问设备的软件。该软件为防火墙外的用户提供了简单、高度安全的访问功能，帮助远程办公人员在他们选择的设备上更有效地工作。 Cisco Expressway Series Traversal Using Relays around NAT 存在安全漏洞，该漏洞源于在受影响的软件内的TURN服务器对特定连接信息的错误验证造成的。攻击者可利用该漏洞绕过安全控制，将网络流量发送到受限目的地。成功利用该漏洞可以让攻击者通过受影响的软件将流量发送到ap以外的目的地
英文描述:
A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker to bypass security controls and send network traffic to restricted destinations. The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access.
