CVE-2018-15391 (CNNVD-201810-186)
中文标题:
Cisco Remote PHY Software 资源管理错误漏洞
英文标题:
Cisco Remote PHY IPv4 Fragment Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Remote PHY Software是美国思科(Cisco)公司的一套基于数字光纤的DOCSIS解决方案。该方案使用以太网PON(EPON)和城域网络等作为传输网络。 Cisco Remote PHY Software中的IPv4碎片处理函数存在资源管理错误漏洞。远程攻击者可通过发送畸形的流量利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in certain IPv4 fragment-processing functions of Cisco Remote PHY Software could allow an unauthenticated, remote attacker to impact traffic passing through a device, potentially causing a denial of service (DoS) condition. The vulnerability is due to the affected software not validating and calculating certain numerical values in IPv4 packets that are sent to an affected device. An attacker could exploit this vulnerability by sending malformed IPv4 traffic to an affected device. A successful exploit could allow the attacker to disrupt the flow of certain IPv4 traffic passing through an affected device, which could result in a DoS condition.
