Summary
o 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.

For information about which Cisco FXOS Software and Cisco NX-OS Software
releases are vulnerable, see the Fixed Software 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 of the Cisco FXOS CLI Configuration
Guide .
fxos# show ldap-server
timeout : 30
port : 0
baseDN :
user profile attribute :
search filter : cn=$userid
use groups : 0
recurse groups : 0
group attribute : memberOf
total number of servers : 1
following LDAP servers are configured:
ldap1:
timeout: 30 port: 389 rootDN: DC=cisco-firepower-aaa1,DC=qalab0,DC=com0,DC=cisco-firepower-aaa2,DC=qalab1,DC=com1,DC=cisco-firepower-aaa3,DC=qalab2,DC=com2,DC=cisco-firepower-aaa4,DC=qalab3,DC=com3,DC=cisco-firepower-aaa5,DC=qalab4,DC=com4,DC=cisco-firepower-aaa6,DC=qalab5,DC=qalab006
enable-ssl: true
.
.
.
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 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) :
nxos-switch# show version
