漏洞描述
中文描述:
Cisco Unified Communications Manager(CUCM,Unified CM,CallManager)是美国思科(Cisco)公司的一款统一通信系统中的呼叫处理组件。该组件提供了一种可扩展、可分布和高可用的企业IP电话呼叫处理解决方案。 Cisco Unified Communications Manager 和 Cisco Unified Communications Manager SME 存在代码问题漏洞,该漏洞源于不正确地处理某些 Cisco 发现协议数据包。攻击者利用此漏洞可以通过不断向受影响的设备发送某些 Cisco 发现协议数据包。成功利用此漏洞可让攻击者在运行受影响软件的系统上造成内核崩溃,从而导致 DoS 状况。
英文描述:
A vulnerability in the Cisco Discovery Protocol of Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, adjacent attacker to cause a kernel panic on an affected system, resulting in a denial of service (DoS) condition. This vulnerability is due to incorrect processing of certain Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by continuously sending certain Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to cause a kernel panic on the system that is running the affected software, resulting in a DoS condition.
