Cisco Security Advisory: Cisco IOS and IOS XE Software Internet Key Exchange Memory Leak Vulnerability
Advisory ID: cisco-sa-20180328-ike
For Public Release: 2018 March 28 16:00 GMT
Last Updated: 2018 March 28 16:00 GMT
CVE ID(s): CVE-2018-0158
CVSS Score v(3): 8.6 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition.
The vulnerability is due to incorrect processing of certain IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
