A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-errdisable [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-errdisable\"]\r\n 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. For a complete list of the advisories and links to them, see Cisco Event Response: September 2018 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication [\"https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-69981\"].", "title": "Summary" }, { "category": "general", "text": "This vulnerability affects Cisco Catalyst 3650, 3850, and 4500E Series Switches that are running a vulnerable release of Cisco IOS XE Software and have the errdisable feature enabled for a feature at both the VLAN and port level.\r\n\r\nFor information about which Cisco IOS XE Software releases are vulnerable, see the Fixed Software [\"#fixed\"] section of this advisory.\r\n Determining Whether a Device Is Running an Affected Configuration\u003c!--3--\u003e\r\nTo determine whether a device is running an affected configuration at both the VLAN and port level, perform both of the following steps:\r\n\r\nStep 1: VLAN Level\r\n\r\nThere are two options for completing Step 1.\r\n\r\nOption A: show errdisable detect\r\n\r\nIssue the CLI command show errdisable detect | include vlan. For each VLAN mode feature that the device lists in the output for this command, perform the corresponding portion of Step 2. The following example shows a device that is configured for a VLAN mode errdisable detect for bpduguard (BPDU guard), psecure-violation (port security violation), and security-violation (802.1x security violation) on the VLAN:\r\n\r\n\r\nswitch#show errdisable detect | include vlan\r\n bpduguard Enabled vlan psecure-violation Enabled port/vlan security-violation Enabled vlan switch#\r\n\r\nOption B: show running-config\r\n\r\nTo determine whether a device is running an affected configuration at the VLAN level, issue the show running-config command twice, using two different include statements:\r\n\r\nFirst, issue the CLI command show running-config | include shutdown vlan. For each VLAN mode feature that the device lists in the output for this command, perform the corresponding portion of Step 2. The following example shows a device that is configured for a VLAN mode errdisable detect for security-violation (802.1x security violation) and bpduguard (BPDU guard) on the VLAN:\r\n\r\nswitch#show running-config | include shutdown vlan\r\n errdisable detect cause security-violation shutdown vlan errdisable detect cause bpduguard shutdown vlan switch#\r\n\r\nSecond, issue the CLI command show running-config | include switchport port-security violation shutdown vlan. If the command returns output, perform the corresponding portion of Step 2. The following example shows a device that is configured for a VLAN mode errdisable detect for port security violation on the VLAN :\r\n\r\nswitch#show running-config | include switchport port-security violation shutdown vlan\r\n switchport port-security violation shutdown vlan switch#\r\n\r\n\r\nStep 2: Port Level\r\n\r\nFor each VLAN mode configured feature revealed in Step 1, do the following to determine whether the feature is also enabled at the port level:\r\n\r\n\r\nBPDU guard: If errdisable per VLAN for detection cause bpduguard is enabled, confirm that the device also has BPDU guard configured. If the configuration contains either of the following, the device is vulnerable:\r\n\r\n\r\nspanning-tree portfast bpduguard default\r\n interface \u003cinterface-id\u003e spanning-tree portfast\r\n\r\nor\r\n\r\n\r\ninterface \u003cinterface-id\u003e\r\n spanning-tree bpduguard enable\r\n\r\n\r\nPort security violation: Errdisable per port/vlan for detection cause psecure-violation is enabled by default. Confirm that the device also has port security configured and violation vlan shutdown configured. If the output of show port-security contains a row with Shutdown Vlan (as shown in the following example), the device is vulnerable:\r\n\r\n\r\nswitch#show port-security\r\nSecure Port MaxSecureAddr CurrentAddr SecurityViolation Security Action (Count) (Count) (Count) --------------------------------------------------------------------------- Gi1/0/48 1 1 5 Shutdown Vlan --------------------------------------------------------------------------- Total Addresses in System (excluding one mac per port) : 0 Max Addresses limit in System (excluding one mac per port) : 4096 switch#\r\n\r\n\r\n802.1x security violation: If errdisable per VLAN for detection cause security-violation is enabled, confirm that the device also has 802.1x authentication configured and the voice VLAN is configured. If the configuration contains the following and does not contain authentication violation {protect|replace|restrict}, the device is vulnerable:\r\n\r\n\r\ninterface \u003cinterface-id\u003e\r\n authentication port-control value switchport voice vlan value\r\n\r\nHowever, if the following content is also present in the CLI output, the device is not vulnerable:\r\n\r\n\r\nauthentication violation {protect|replace|restrict}\r\n\r\n Determining the Cisco IOS XE Software Release\r\nTo 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. If the device is running Cisco IOS XE Software, the system banner displays Cisco IOS Software, Cisco IOS XE Software, or similar text.\r\n\r\nThe 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:\r\n\r\n\r\nios-xe-device# show version\r\n Cisco IOS Software, Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M), Version Denali 16.2.1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2016 by Cisco Systems, Inc.
