Published: 2016-05-04 16:54:26
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Detection Method:
Checks if a vulnerable version is present on the target host.

Recommendations:
See the referenced vendor advisory for a solution.

Summary:
A vulnerability in the Internet Key Exchange (IKE) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to delete established security associations on an affected device. The vulnerability is due to improper handling of rogue IKE Main Mode packets. An attacker could exploit this vulnerability by sending a crafted IKE Main Mode packet to an affected device. An exploit could allow the attacker to cause valid, established IKE security associations on an affected device to drop. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker may need access to trusted, internal networks to send crafted IKE Main Mode packets to a targeted device. This access requirement may reduce the possibility of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists, however, the code is not known to be publicly available.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
