Cisco NX-OS Software NX-API Remote Code Execution Vulnerability
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-napi-rce-r2shwu2j?vs_f=Cisco%20Security%20Advisory%26vs_cat=Security%20Intelligence%26vs_type=RSS%26vs_p=Cisco%20NX-OS%20Software%20NX-API%20Remote%20Code%20Execution%20Vulnerability%26vs_k=1
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to insufficient input validation of data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Nexus 3000 and 9000 Series Switches NGOAM Remote Code Execution Vulnerabilities
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ngoam-rce-LWKQ4BU?vs_f=Cisco%20Security%20Advisory%26vs_cat=Security%20Intelligence%26vs_type=RSS%26vs_p=Cisco%20Nexus%203000%20and%209000%20Series%20Switches%20NGOAM%20Remote%20Code%20Execution%20Vulnerabilities%26vs_k=1
Multiple vulnerabilities in the Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as Next Generation OAM (NGOAM), could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.
These vulnerabilities are due to improper input validation of IP traffic when NGOAM is enabled. An attacker could exploit these vulnerabilities by sending crafted packets to an IP interface on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition.
Note: Feature requirements vary for each vulnerability.

Cisco NX-OS Software Control Plane Denial of Service Vulnerability
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-nscpdos-SnderkC7?vs_f=Cisco%20Security%20Advisory%26vs_cat=Security%20Intelligence%26vs_type=RSS%26vs_p=Cisco%20NX-OS%20Software%20Control%20Plane%20Denial%20of%20Service%20Vulnerability%26vs_k=1
A vulnerability in Cisco NX-OS Software could allow an unauthenticated, remote attacker to exhaust system resources, causing a denial of service (DoS) condition.
This vulnerability exists because rate limiting was improperly applied to some protocols. An attacker could exploit this vulnerability by sending a high rate of UDP or TCP connections to a data plane interface on an affected device. A successful exploit could allow the attacker to cause instability to various routing and control plane protocols through some packet loss and temporary disruptions, causing a DoS condition. This DoS condition will clear without manual intervention soon after the high rate of traffic is stopped.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
