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 •
CVSS: 5.8EPSS: 0%CPEs: 69EXPL: 0CVE-2019-1969 – Cisco NX-OS Software SNMP Access Control List Configuration Name Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1969
A vulnerability in the implementation of the Simple Network Management Protocol (SNMP) Access Control List (ACL) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to perform SNMP polling of an affected device, even if it is configured to deny SNMP traffic. The vulnerability is due to an incorrect length check when the configured ACL name is the maximum length, which is 32 ASCII characters. An attacker could exploit this vulnerability by performing SNMP polling of an affected device. A successful exploit could allow the attacker to perform SNMP polling that should have been denied. The attacker has no control of the configuration of the SNMP ACL name. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-nxos-snmp-bypass • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.5EPSS: 0%CPEs: 26EXPL: 0CVE-2019-1977 – Cisco Nexus 9000 Series Fabric Switches ACI Mode Border Leaf Endpoint Learning Vulnerability
https://notcve.org/view.php?id=CVE-2019-1977
A vulnerability within the Endpoint Learning feature of Cisco Nexus 9000 Series Switches running in Application Centric Infrastructure (ACI) mode could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an endpoint device in certain circumstances. The vulnerability is due to improper endpoint learning when packets are received on a specific port from outside the ACI fabric and destined to an endpoint located on a border leaf when Disable Remote Endpoint Learning has been enabled. This can result in a Remote (XR) entry being created for the impacted endpoint that will become stale if the endpoint migrates to a different port or leaf switch. This results in traffic not reaching the impacted endpoint until the Remote entry can be relearned by another mechanism. Una vulnerabilidad dentro de la funcionalidad Endpoint Learning de Cisco Nexus 9000 Series Switches ejecutándose en el modo Application Centric Infrastructure (ACI), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en dispositivo endpoint en determinadas circunstancias. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-nexus-aci-dos • CWE-371: State Issues •
