CVSS: 7.8EPSS: 0%CPEs: 171EXPL: 0CVE-2023-20050 – Cisco NX-OS Software CLI Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2023-20050
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient validation of arguments that are passed to specific CLI commands. An attacker could exploit this vulnerability by including crafted input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with the privileges of the currently logged-in user. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-cli-cmdinject-euQVK9u • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 8.6EPSS: 0%CPEs: 33EXPL: 0CVE-2022-20623 – Cisco Nexus 9000 Series Switches Bidirectional Forwarding Detection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20623
A vulnerability in the rate limiter for Bidirectional Forwarding Detection (BFD) traffic of Cisco NX-OS Software for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to cause BFD traffic to be dropped on an affected device. This vulnerability is due to a logic error in the BFD rate limiter functionality. An attacker could exploit this vulnerability by sending a crafted stream of traffic through the device. A successful exploit could allow the attacker to cause BFD traffic to be dropped, resulting in BFD session flaps. BFD session flaps can cause route instability and dropped traffic, resulting in a denial of service (DoS) condition. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-bfd-dos-wGQXrzxn • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2022-20624
A vulnerability in the Cisco Fabric Services over IP (CFSoIP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of incoming CFSoIP packets. An attacker could exploit this vulnerability by sending crafted CFSoIP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en la función Cisco Fabric Services over IP (CFSoIP) del software Cisco NX-OS podría permitir a un atacante remoto no autenticado provocar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cfsoip-dos-tpykyDr • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.1EPSS: 0%CPEs: 118EXPL: 0CVE-2022-20625 – Cisco FXOS and NX-OS Software Cisco Discovery Protocol Service Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20625
A vulnerability in the Cisco Discovery Protocol service of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause the service to restart, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of Cisco Discovery Protocol messages that are processed by the Cisco Discovery Protocol service. An attacker could exploit this vulnerability by sending a series of malicious Cisco Discovery Protocol messages to an affected device. A successful exploit could allow the attacker to cause the Cisco Discovery Protocol service to fail and restart. In rare conditions, repeated failures of the process could occur, which could cause the entire device to restart. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cdp-dos-G8DPLWYG • CWE-399: Resource Management Errors •
CVSS: 9.0EPSS: 0%CPEs: 67EXPL: 0CVE-2022-20650 – Cisco NX-OS Software NX-API Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2022-20650
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an authenticated, remote attacker to execute arbitrary commands with root privileges. The vulnerability is due to insufficient input validation of user supplied data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP POST request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying operating system. Note: The NX-API feature is disabled by default. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-nxapi-cmdinject-ULukNMZ2 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
