Summary
Cisco NX-OS Software Protocol Independent Multicast Denial of Service Vulnerability

Notes

Summary
A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted PIM packet to an affected device. A successful exploit could allow the attacker to cause a traffic loop, resulting in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-pim-dos-Y8SjMz4 ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-pim-dos-Y8SjMz4"]
Vulnerable Products
At the time of publication, this vulnerability affected Cisco Nexus 9500 R-Series Switching Platforms if they were running a vulnerable release of Cisco NX-OS Software and had the feature pim command configured. For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory. Note: No other Cisco Nexus 9000 Series Switches in standalone NX-OS mode are affected by this vulnerability.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect the following Cisco products: Firepower 1000 Series Firepower 2100 Series Firepower 4100 Series Firepower 9300 Security Appliances MDS 9000 Series Multilayer Switches Nexus 1000 Virtual Edge for VMware vSphere Nexus 1000V Switch for Microsoft Hyper-V Nexus 1000V Switch for VMware vSphere Nexus 3000 Series Switches Nexus 5500 Platform Switches Nexus 5600 Platform Switches Nexus 6000 Series Switches Nexus 7000 Series Switches Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode UCS 6200 Series Fabric Interconnects UCS 6300 Series Fabric Interconnects UCS 6400 Series Fabric Interconnects
Workarounds
There are no workarounds that address this vulnerability.
Fixed Software
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In 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. Cisco NX-OS Software To help customers determine their exposure to vulnerabilities in Cisco NX-OS Software, Cisco provides the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] to identify any Cisco Security Advisories that impact a specific Cisco NX-OS Software release and the earliest release that fixes the vulnerabilities that are described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (“Combined First Fixed”). Customers can use the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] to search advisories in the following ways: Choose the software, platform, and one or more releases Upload a .txt file that includes a list of specific releases Enter the output of the show version command After initiating a search, customers can customize the search to include all Cisco Security Advisories or one or more specific advisories. Customers can also use the following form to determine whether a release is affected by any Cisco Security Advisory by choosing the Cisco NX-OS Software and platform and then entering a release—for example, 7.0(3)I7(5) for Cisco Nexus 3000 Series Switches or 14.0(1h) for Cisco NX-OS Software in ACI mode: Cisco NX-OS Software Cisco NX-OS Software in ACI Mode MDS 9000 Series Multilayer Switches Nexus 1000V Series Switches Nexus 3000 Series Switches Nexus 5000 Series Switches Nexus 6000 Series Switches Nexus 7000 Series Switches Nexus 9000 Series Switches By default, the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] includes results only for vulnerabilities that have a Critical or High Security Impact Rating (SIR). To include results for Medium SIR vulnerabilities, customers can use the Cisco Software Checker and check the Medium check box in the drop-down list under Impact Rating when customizing a search. Additional Resources For help determining the best Cisco NX-OS Software release for a Cisco Nexus Switch, see the following Recommended Releases documents. If a security advisory recommends a later release, Cisco recommends following the advisory guidance. Cisco MDS Series Switches ["https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/b_MDS_NX-OS_Recommended_Releases.html"] Cisco Nexus 1000V for VMware Switch ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus1000/sw/recommended_releases/b_Cisco_N1KV_VMware_MinRecommendedReleases.html"] Cisco Nexus 3000 Series Switches ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/recommended_release/b_Minimum_and_Recommended_Cisco_NX-OS_Releases_for_Cisco_Nexus_3000_Series_Switches.html"] Cisco Nexus 5500 Platform Switches ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/release/recommended_releases/n5500_recommended_nx-os_releases.html"] Cisco Nexus 5600 Platform Switches ["https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5600/sw/release/recommended_releases/n5600_recommended_nx-os_releases.html"] Cisco Nexus 6000 Series Switches ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus6000/sw/release/recommended_releases/recommended_nx-os_releases.html"] Cisco Nexus 7000 Series Switches ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/recommended_releases/recommended_nx-os_releases.html"] Cisco Nexus 9000 Series Switches ["http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/recommended_release/b_Minimum_and_Recommended_Cisco_NX-OS_Releases_for_Cisco_Nexus_9000_Series_Switches.html"] Cisco Nexus 9000 Series ACI-Mode Switches ["https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/recommended-release/b_Recommended_Cisco_ACI_Releases.html"] To determine the best release for Cisco UCS Software, see the Recommended Releases documents in the release notes for the device.
