Summary
Cisco NX-OS Software Command Injection Vulnerability (CVE-2019-1784)

Notes

Summary
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with the privilege level of root. The vulnerability is due to insufficient validation of arguments passed to a specific CLI command on the affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

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 No upgrade action is necessary for customers who have already applied a recommended release to address the March 2019 Cisco FXOS and NX-OS Software bundle. See Cisco Event Response: March 2019 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-70757"] for a list of advisories in the bundle. Customers who have not applied a recommended release to address the March 2019 bundle 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 applicable table in this section.

        "text": "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\"]\r\n\r\nAdditionally, 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.\r\n\r\nWhen 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.\r\n\r\nIn 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.\r\n  Customers Without Service Contracts\r\nCustomers 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\"]\r\n\r\nCustomers 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.\r\n  Fixed Releases\r\nNo upgrade action is necessary for customers who have already applied a recommended release to address the March 2019 Cisco FXOS and NX-OS Software bundle. See  Cisco Event Response: March 2019 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication [\"https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-70757\"] for a list of advisories in the bundle.\r\n\r\nCustomers who have not applied a recommended release to address the March 2019 bundle 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 applicable table in this section.
