Cisco ASA Software and Cisco ASA 5500-X Series with Firepower Threat Defense Software The following example shows the output of the command for a device that is running Cisco IOS XE Software Release 16.2.1 and has an installed image name of CAT3K_CAA-UNIVERSALK9-M: ios-xe-device# show versionĬisco IOS Software, Catalyst 元 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version Denali 16.2.1, RELEASE SOFTWARE (fc1)Ĭopyright (c) 1986-2016 by Cisco Systems, Inc.įor information about the naming and numbering conventions for Cisco IOS XE Software releases, see the Cisco IOS and NX-OS Software Reference Guide.
If the device is running Cisco IOS XE Software, the system banner displays Cisco IOS Software, Cisco IOS XE Software, or similar text. To determine which Cisco IOS XE Software release is running on a device, administrators can log in to the device, use the show version command in the CLI, and then refer to the system banner that appears.

This advisory is part of the September 26, 2018, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes 12 Cisco Security Advisories that describe 13 vulnerabilities.
This advisory is available at the following link: There are no workarounds that address this vulnerability. An exploit could allow the attacker to cause a reload of the affected device.Ĭisco has released software updates that address this vulnerability. An attacker could exploit this vulnerability by sending malformed IPsec packets to be processed by an affected device. The vulnerability is due to improper processing of malformed IPsec Authentication Header (AH) or Encapsulating Security Payload (ESP) packets.
