Summary
Cisco FXOS and NX-OS Lightweight Directory Access Protocol Denial of Service Vulnerabilities
Notes
Summary
Multiple vulnerabilities in the implementation of the Lightweight Directory Access Protocol (LDAP) feature in Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.
The vulnerabilities are due to the improper parsing of LDAP packets by an affected device. An attacker could exploit these vulnerabilities by sending an LDAP packet crafted using Basic Encoding Rules (BER) to an affected device. The LDAP packet must have a source IP address of an LDAP server configured on the targeted device. A successful exploit could cause the affected device to reload, resulting in a DoS condition.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
This advisory is available at the following link:

For information about which Cisco FXOS Software and Cisco NX-OS Software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
Determining the Cisco FXOS LDAP Configuration
To determine whether a Nexus device is configured for LDAP-based authentication, authorization, and accounting (AAA), administrators can use the show ldap-server CLI command. Output after the following LDAP servers are configured header indicates that a device is vulnerable. For additional information about AAA configuration for FXOS-based devices, customers can refer to the Configuring AAA section ["https://www.cisco.com/c/en/us/td/docs/security/firepower/fxos/fxos201/cli-config/b_CLI_ConfigGuide_FXOS_201/platform_settings.html#topic_105C66CC3C7F4D99B08A413FEF5BCEF4"] of the Cisco FXOS CLI Configuration Guide.

Determining the Cisco NX-OS LDAP Configuration
To determine whether a Nexus device is configured for the LDAP feature, administrators can use the show running-config | include "ldap-server host" command from the NX-OS CLI and verify that the feature is enabled.
nxos-switch# show running-config | include "ldap-server host"
ldap-server host ...
For additional information on NX-OS LDAP configuration, customers can refer to the Configuring LDAP chapter ["https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/5_x/nx-os/security/configuration/guide/b_Cisco_Nexus_7000_NX-OS_Security_Configuration_Guide__Release_5-x/b_Cisco_Nexus_7000_NX-OS_Security_Configuration_Guide__Release_5-x_chapter_0111.html#con_1473592"] of the Cisco Security Configuration Guide.
Determining the Cisco FXOS Software Release
Administrators can check the release of Cisco FXOS Software that is running on a device by using the following commands in the device CLI or by navigating to the Overview tab in the Admin portal. The following example shows the output of the show version CLI command on a device that is running Cisco FXOS Software Release 2.2(2.14), as identified in the Package-Vers field of the command output:
QP4120B1 # scope system
QP4120B1 /system # show version FPRM: Running-Vers: 4.2(2.15) Package-Vers: 2.2(2.14) Activate-Status: Ready
Determining the Cisco NX-OS Software Release
Administrators can check the release of Cisco NX-OS Software that is running on a device by using the show version command in the device CLI. The following example shows the output of this command on a device that is running Cisco NX-OS Software Release 7.0(3)I5(1):

"text": "Cisco has released free software updates that address the vulnerabilities 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\n\r\nCustomers 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. To help ensure a complete upgrade solution, customers should consider that this advisory is part of a bundled publication.
