Cisco IOS XE Software IP Service Level Agreements Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS和IOS XE都是美国思科(Cisco)公司的产品。CLI是其中的一个命令行界面。 Cisco IOS XE Software IP Service Level Agreement (SLA)中存在安全漏洞,该漏洞源于IP SLA响应器可能占用了另一个功能可以使用的端口,该漏洞允许攻击者通过将特定的IP SLA控制数据包发送到受影响设备上的IP SLA响应程序来利用此漏洞。
英文描述:
A vulnerability in the IP Service Level Agreement (SLA) responder feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the IP SLA responder to reuse an existing port, resulting in a denial of service (DoS) condition. The vulnerability exists because the IP SLA responder could consume a port that could be used by another feature. An attacker could exploit this vulnerability by sending specific IP SLA control packets to the IP SLA responder on an affected device. The control packets must include the port number that could be used by another configured feature. A successful exploit could allow the attacker to cause an in-use port to be consumed by the IP SLA responder, impacting the feature that was using the port and resulting in a DoS condition.
