漏洞描述信息
Cisco Webex Room Phone 和 Cisco Webex Share 设备中的链路层发现协议(LLDP)功能的一个漏洞可能导致未授权的相邻攻击者在网络受影响的设备上引起服务拒绝(DoS)状态。这个漏洞是由于资源分配不足引起的。攻击者可以通过向受影响的设备发送精心构造的 LLDP 流量来利用此漏洞。一个成功的利用可能导致攻击者耗尽受影响设备内存资源，最终导致 LLDP 进程崩溃。如果受影响的设备被配置为仅支持 LLDP，这可能导致进口和出口通话中断。默认情况下，这些设备被配置为支持 both Cisco Discovery Protocol 和 LLDP。为了恢复操作状态，受影响的设备需要手动重启。

漏洞描述信息
A vulnerability in the Link Layer Discovery Protocol (LLDP) feature of Cisco Webex Room Phone and Cisco Webex Share devices could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to insufficient resource allocation. An attacker could exploit this vulnerability by sending crafted LLDP traffic to an affected device. A successful exploit could allow the attacker to exhaust the memory resources of the affected device, resulting in a crash of the LLDP process. If the affected device is configured to support LLDP only, this could cause an interruption to inbound and outbound calling. By default, these devices are configured to support both Cisco Discovery Protocol and LLDP. To recover operational state, the affected device needs a manual restart.
