Cisco Security Advisory: Cisco FXOS and NX-OS Software Cisco Fabric Services Arbitrary Code Execution Vulnerability
Advisory ID: cisco-sa-20180620-fx-os-fabric-execution
Revision: 1.0
For Public Release: 2018 June 20 16:00 GMT
Last Updated: 2018 June 20 16:00 GMT
CVE ID(s): CVE-2018-0314
CVSS Score v(3): 9.8 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
+———————————————————————
Summary
=======
A vulnerability in the Cisco Fabric Services (CFS) component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device.
The vulnerability exists because the affected software insufficiently validates Cisco Fabric Services packet headers when the software processes packet data. An attacker could exploit this vulnerability by sending a maliciously crafted Cisco Fabric Services packet to an affected device. A successful exploit could allow the attacker to cause a buffer overflow condition on the device, which could allow the attacker to execute arbitrary code on the device.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

This advisory is part of the June 2018 Cisco FXOS and NX-OS Software Security Advisory Collection, which includes 24 Cisco Security Advisories that describe 24 vulnerabilities.

Summary
=======
A vulnerability in the Cisco Fabric Services component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to read sensitive memory content, create a denial of service (DoS) condition, or execute arbitrary code as root.
The vulnerability exists because the affected software insufficiently validates Cisco Fabric Services packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Fabric Services packet to an affected device. A successful exploit could allow the attacker to cause a buffer overflow or buffer overread condition in the Cisco Fabric Services component, which could allow the attacker to read sensitive memory content, create a DoS condition, or execute arbitrary code as root.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
