CVSS: 8.8EPSS: 0%CPEs: 120EXPL: 0CVE-2020-3119 – Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3119
A vulnerability in the Cisco Discovery Protocol implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability exists because the Cisco Discovery Protocol parser does not properly validate input for certain fields in a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. An successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device. Cisco Discovery Protocol is a Layer 2 protocol. • http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-nxos-cdp-rce • CWE-787: Out-of-bounds Write •
CVSS: 7.4EPSS: 0%CPEs: 208EXPL: 0CVE-2020-3120 – Cisco FXOS, IOS XR, and NX-OS Software Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3120
A vulnerability in the Cisco Discovery Protocol implementation for Cisco FXOS Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing check when the affected software processes Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to exhaust system memory, causing the device to reload.

CVSS: 7.8EPSS: 0%CPEs: 92EXPL: 0CVE-2019-12717 – Cisco NX-OS Software Virtualization Manager Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-12717
A vulnerability in a CLI command related to the virtualization manager (VMAN) in Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying Linux operating system with root privileges. The vulnerability is due to insufficient validation of arguments passed to a specific VMAN CLI command on an affected device. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system with root privileges, which may lead to complete system compromise. An attacker would need valid administrator credentials to exploit this vulnerability. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-nxos-vman-cmd-inj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.2EPSS: 0%CPEs: 138EXPL: 0CVE-2019-12662 – Cisco NX-OS and IOS XE Software Virtual Service Image Signature Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-12662
A vulnerability in Cisco NX-OS Software and Cisco IOS XE Software could allow an authenticated, local attacker with valid administrator or privilege level 15 credentials to load a virtual service image and bypass signature verification on an affected device. The vulnerability is due to improper signature verification during the installation of an Open Virtual Appliance (OVA) image. An authenticated, local attacker could exploit this vulnerability and load a malicious, unsigned OVA image on an affected device. A successful exploit could allow an attacker to perform code execution on a crafted software OVA image. Una vulnerabilidad en el Software Cisco NX-OS y el Software Cisco IOS XE, podría permitir que un atacante local autenticado con credenciales válidas de administrador o nivel de privilegio 15 cargue una imagen de servicio virtual y omita la comprobación de firma en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-vman • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.5EPSS: 0%CPEs: 114EXPL: 0CVE-2019-1968 – Cisco NX-OS Software NX-API Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1968
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an NX-API system process to unexpectedly restart. The vulnerability is due to incorrect validation of the HTTP header of a request that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API on an affected device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition in the NX-API service; however, the NX-OS device itself would still be available and passing network traffic. Note: The NX-API feature is disabled by default. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-nxos-api-dos • CWE-20: Improper Input Validation CWE-116: Improper Encoding or Escaping of Output •
