漏洞描述
中文描述:
Cisco IOS XR是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。 Cisco IOS XR(配置有SNMP 1版本、2c版本或3版本)中(IS-IS)路由协议的实现存在输入验证错误漏洞,该漏洞源于IS-IS进程没有正确处理SNMP请求。远程攻击者可借助特制的SNMP请求利用该漏洞造成拒绝服务。以下产品及版本受到影响:Cisco IOS XR 6.6.3之前版本,7.0.2之前版本,7.1.1之前版本,7.2.1之前版本。
英文描述:
A vulnerability in the implementation of the Intermediate System–to–Intermediate System (IS–IS) routing protocol functionality in Cisco IOS XR Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition in the IS–IS process. The vulnerability is due to improper handling of a Simple Network Management Protocol (SNMP) request for specific Object Identifiers (OIDs) by the IS–IS process. An attacker could exploit this vulnerability by sending a crafted SNMP request to the affected device. A successful exploit could allow the attacker to cause a DoS condition in the IS–IS process.
