The vulnerability is due to incorrect processing of certain CDP packets. An attacker could exploit this vulnerability by sending certain CDP packets to an affected device.

    "data": "A vulnerability in the Cisco Discovery Protocol (CDP) module of Cisco IOS XE Software Releases 16.6.1 and 16.6.2 could allow an unauthenticated, adjacent attacker to cause a memory leak that may lead to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain CDP packets. An attacker could exploit this vulnerability by sending certain CDP packets to an affected device. A successful exploit could cause an affected device to continuously consume memory and eventually result in a memory allocation failure that leads to a crash, triggering a reload of the affected device. Cisco IOS XE The software is vulnerable to resource exhaustion.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco IOSXESoftware is a set of operating systems developed by Cisco for its network devices. Cisco Discovery Protocol (CDP) is one of the device discovery modules. An attacker with a physical location nearby can exploit the vulnerability to cause a denial of service (crash). \nAttackers can exploit this issue to reload the affected device, denying service to legitimate users\nThis issue is being tracked by Cisco Bug ID CSCvf50648",

An attacker could exploit this vulnerability by  sending certain CDP packets to an affected device. A successful exploit  could cause an affected device to continuously consume memory and  eventually result in a memory allocation failure that leads to a crash,  triggering a reload of the affected device.\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-cdp-memleak [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cdp-memleak\"]\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.

The CDP feature is enabled in Cisco IOS XE on all interfaces by default.\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 the CDP Feature Is Enabled\r\nTo determine whether a device is configured with the CDP feature enabled globally, use the show running-config all | include cdp run privileged EXEC command on the device.

The following example shows the output of the show cdp interface command on a device that has the CDP feature disabled on all interfaces:\r\n\r\n\r\n\r\n\r\nios-xe-device#show cdp interface\r\n% CDP is not enabled\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.

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:\r\nhttps://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\r\nCustomers Without Service Contracts\r\n\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:\r\nhttps://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                          Cisco IOS and IOS XE Software\r\nTo help customers determine their exposure to vulnerabilities in Cisco IOS and IOS XE Software, Cisco provides a tool, the Cisco IOS Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"], that identifies any Cisco Security Advisories that impact a specific software release and the earliest release that fixes the vulnerabilities described in each advisory (\u201cFirst Fixed\u201d). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (\u201cCombined First Fixed\u201d).\r\n\r\nCustomers can use this tool to perform the following tasks:\r\n\r\nInitiate a search by choosing one or more releases from a drop-down list or uploading a file from a local system for the tool to parse\r\nEnter the output of the show version command for the tool to parse\r\nCreate a custom search by including all previously published Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication\r\n\r\nTo determine whether a release is affected by any published Cisco Security Advisory, use the Cisco IOS Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] on Cisco.com or enter a Cisco IOS Software or Cisco IOS XE Software release\u2014for example, 15.1(4)M2 or 3.13.8S\u2014in the following field:\r\n\r\n\r\n\r\nBy default, the Cisco IOS Software Checker includes results only for vulnerabilities that have a Critical or High Security Impact Rating (SIR). To include results for Medium SIR vulnerabilities, use the Cisco IOS Software Checker on Cisco.com and check the Medium check box in the Impact Rating drop-down list.\r\n\r\nFor a mapping of Cisco IOS XE Software releases to Cisco IOS Software releases, refer to the Cisco IOS XE 2 Release Notes [\"https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/2/release/notes/rnasr21/rnasr21_gen.html#wp3000032\"], Cisco IOS XE 3S Release Notes [\"https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/3/release/notes/asr1k_rn_3s_rel_notes/asr1k_rn_3s_sys_req.html#wp3069754\"], or Cisco IOS XE 3SG Release Notes [\"https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_24726.html#pgfId-2570252\"], depending on the Cisco IOS XE Software release.",
