Summary
Cisco Nexus 3000 Series and 9000 Series Switches in NX-OS Mode CLI Command Software Image Signature Verification Vulnerability
Notes
Summary
A vulnerability in the Image Signature Verification feature used in an NX-OS CLI command in Cisco Nexus 3000 Series and 9000 Series Switches could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device.
The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device.
Note: If the device has not been patched for the vulnerability previously disclosed in the Cisco Security Advisory cisco-sa-20190306-nxos-sig-verif ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-sig-verif"], a successful exploit could allow the attacker to boot a malicious software image.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Vulnerable Products
This vulnerability affects the following Cisco products if they are running a vulnerable release of Cisco NX-OS Software:
Nexus 3000 Series Switches with the following product IDs (PIDs):
N3K-C3164Q
N3K-C3232C
Nexus 9000 Series Switches in standalone NX-OS mode with the following PIDs:
N9K-C92304QC
N9K-C9232C
Note: This vulnerability affects a limited number of products; only the preceding PIDs are affected by this vulnerability.
For information about which Cisco NX-OS Software releases are vulnerable, see the Fixed Software ["https://tvce.cisco.com/security/AIMS/SecurityPublicationDetail.aspx?Mode=Edit&ID=71204&Version=1&Revision=8#fs"] section of this advisory.
Determining the Cisco NX-OS Product ID
To check the PID, administrators can use the show inventory command in the device CLI. The following example shows the output of the command for a device that has the PID N3K-C3232C:
switch# show inventory
NAME: "Chassis", DESCR: "Nexus3000 C3232C Chassis" PID: N3K-C3232C , VID: V02 , SN: FOC20291JA0 NAME: "Slot 1", DESCR: "32x40/100G QSFP28 2x10G SFP+ Ethernet Module" PID: N3K-C3232C , VID: V02 , SN: FOC20291JA0 NAME: "Power Supply 1", DESCR: "Nexus3000 C3232C Chassis Power Supply" PID: NXA-PAC-650W-PI , VID: V01 , SN: LIT20362Z6G

Workarounds
There are no workarounds that address this vulnerability.
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, 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.
Fixed Releases
Customers are advised to upgrade to an appropriate release ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"] as indicated in the following table. In the table, the left column lists the affected PIDs. The first affected Cisco NX-OS Software releases for each PID are in the center column. The right column indicates the first release that includes the fix for this vulnerability.
Note: A complete fix for this vulnerability requires that a proper BIOS version is installed. Customers who are running a vulnerable PID listed in the following table may not have upgraded the BIOS when the software was installed even if they are running a fixed software release. Customers are advised to confirm that the BIOS is running a fixed BIOS version (first fixed or later) as described in the previously disclosed Cisco Security Advisory cisco-sa-20190306-nxos-sig-verif ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-sig-verif"].
