CVE-2019-1910 (CNNVD-201908-534)
中文标题:
Cisco IOS XR 输入验证错误漏洞
英文标题:
Cisco IOS XR Software Intermediate System to Intermediate System Denial of Service Vulnerability
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 6.6.3之前版本中的中间系统到中间系统(IS–IS)路由协议功能存在输入验证错误漏洞,该漏洞源于程序没有正确处理特制的链路状态协议数据单元(PDUs)。攻击者可通过发送特制的链路状态协议数据单元利用该漏洞造成拒绝服务。
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 unauthenticated attacker who is in the same IS–IS area to cause a denial of service (DoS) condition. The vulnerability is due to incorrect processing of crafted IS–IS link-state protocol data units (PDUs). An attacker could exploit this vulnerability by sending a crafted link-state PDU to an affected system to be processed. A successful exploit could allow the attacker to cause all routers within the IS–IS area to unexpectedly restart the IS–IS process, resulting in a DoS condition. This vulnerability affects Cisco devices if they are running a vulnerable release of Cisco IOS XR Software earlier than Release 6.6.3 and are configured with the IS–IS routing protocol. Cisco has confirmed that this vulnerability affects both Cisco IOS XR 32-bit Software and Cisco IOS XR 64-bit Software.
