Vulnerability Details

Cisco NX-OS Software Fibre Channel over Ethernet Denial of Service Vulnerability

Published: 2017-06-08 05:12:26
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:A/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 Fibre Channel over Ethernet (FCoE) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when an FCoE-related process unexpectedly reloads.

Technical Details:
The vulnerability is due to a lack of proper FCoE frame padding validation. An attacker could exploit this vulnerability by sending a stream of crafted FCoE frames to the targeted device. The attacker's server must be directly connected to the FCoE interface on the device that is running Cisco NX-OS Software to exploit this vulnerability.

Impact:
An exploit could allow the attacker to cause a DoS condition, which would impact FCoE traffic passing through the device.

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".
