Summary
Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution Vulnerability
Notes
Summary
A vulnerability in the Cisco Discovery Protocol implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device.
The vulnerability exists because the Cisco Discovery Protocol parser does not properly validate input for certain fields in a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. An successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device.
Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-nxos-cdp-rce ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-nxos-cdp-rce"]
Vulnerable Products
This vulnerability affects the following Cisco products if they have Cisco Discovery Protocol enabled both globally and on at least one interface and if they are running a vulnerable release of Cisco NX-OS Software:
Nexus 3000 Series Switches
Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode
Nexus 9000 Series Switches in standalone NX-OS mode
Note: Cisco Discovery Protocol is enabled on these products by default both globally and on all interfaces.
For information about which Cisco NX-OS Software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
Determine the Status of Cisco Discovery Protocol for Cisco Nexus Switches That Are Running Cisco NX-OS Software
Administrators can determine whether Cisco Discovery Protocol is enabled on a device by using the show running-config cdp all | include “cdp enable” command in the device CLI. If the command returns at least the following lines, Cisco Discovery Protocol is enabled globally and on at least one interface:
nxos# show running-config cdp all | include "cdp enable"
cdp enable cdp enable
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability.
Cisco has confirmed that this vulnerability does not affect the following Cisco products:
Firepower 1000 Series
Firepower 2100 Series
Firepower 4100 Series
Firepower 9300 Security Appliances
MDS 9000 Series Multilayer Switches
Nexus 1000 Virtual Edge for VMware vSphere
Nexus 1000V Switch for Microsoft Hyper-V
Nexus 1000V Switch for VMware vSphere
Nexus 5500 Platform Switches1
Nexus 5600 Platform Switches1
Nexus 6000 Series Switches1
Nexus 7000 Series Switches
UCS 6200 Series Fabric Interconnects1
UCS 6300 Series Fabric Interconnects1
UCS 6400 Series Fabric Interconnects1
1. Earlier versions of this security advisory reported Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, and UCS 6200 Series, 6300 Series, and 6400 Series Fabric Interconnects as affected by this vulnerability. This information was incorrect.
Cisco has also confirmed that this vulnerability does not affect Cisco IOS Software, Cisco IOS XE Software, or Cisco IOS XR Software.
Workarounds
There are no workarounds that address this vulnerability.
However, customers who do not use Cisco Discovery Protocol can disable it either globally to fully close the attack vector or on individual interfaces to reduce the attack surface. Disable Cisco Discovery Protocol Globally on Cisco Nexus Switches That Are Running Cisco NX-OS Software
To disable Cisco Discovery Protocol globally on Cisco Nexus Switches that are running Cisco NX-OS Software, administrators can use the no cdp enable command in global configuration mode, as shown in the following example:
nxos# conf t
Enter configuration commands, one per line. End with CNTL/Z.
nxos(config)# no cdp enable
nxos(config)# end
nxos# copy running-config startup-config
[########################################] 100%
Copy complete.
Disable Cisco Discovery Protocol on an Interface on Cisco Nexus Switches That Are Running Cisco NX-OS Software
To disable Cisco Discovery Protocol on an interface on Cisco Nexus Switches that are running Cisco NX-OS Software, administrators can use the no cdp enable command in interface configuration mode, as shown in the following example:
nxos# conf t
Enter configuration commands, one per line. End with CNTL/Z.
nxos(config)# interface Ethernet1/1
nxos(config-if)# no cdp enable
nxos(config-if)# end
nxos# copy running-config startup-config
[########################################] 100%
Copy complete.
Fixed Software
Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
https://www.cisco.com/c/en/us/products/end-user-license-agreement.html ["https://www.cisco.com/c/en/us/products/end-user-license-agreement.html"]
Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
Customers Without Service Contracts
Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC:
https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"]
Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.
