中文标题:
Cisco IOS XR 输入验证错误漏洞
英文标题:
Cisco IOS XR Software Border Gateway Protocol 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中的Border Gateway Protocol (BGP)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BGP更新消息。远程攻击者可通过发送BGP更新消息利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the implementation of Border Gateway Protocol (BGP) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to incorrect processing of certain BGP update messages. An attacker could exploit this vulnerability by sending BGP update messages that include a specific set of attributes to be processed by an affected system. A successful exploit could allow the attacker to cause the BGP process to restart unexpectedly, resulting in a DoS condition. The Cisco implementation of BGP accepts incoming BGP traffic from explicitly defined peers only. To exploit this vulnerability, the malicious BGP update message would need to come from a configured, valid BGP peer or would need to be injected by the attacker into the victim's BGP network on an existing, valid TCP connection to a BGP peer.
