CVE-2020-3454 – Cisco NX-OS Software Call Home Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2020-3454
A vulnerability in the Call Home feature of Cisco NX-OS Software could allow an authenticated, remote attacker to inject arbitrary commands that could be executed with root privileges on the underlying operating system (OS). The vulnerability is due to insufficient input validation of specific Call Home configuration parameters when the software is configured for transport method HTTP. An attacker could exploit this vulnerability by modifying parameters within the Call Home configuration on an affected device. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying OS. Una vulnerabilidad en la funcionalidad Call Home de Cisco NX-OS Software, podría permitir a un atacante remoto autenticado inyectar comandos arbitrarios que podrían ser ejecutados con privilegios root en el sistema operativo (SO) subyacente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-callhome-cmdinj-zkxzSCY • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2020-3504 – Cisco UCS Manager Software Local Management CLI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3504
A vulnerability in the local management (local-mgmt) CLI of Cisco UCS Manager Software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of CLI command parameters. An attacker could exploit this vulnerability by executing specific commands on the local-mgmt CLI on an affected device. A successful exploit could allow the attacker to cause internal system processes to fail to terminate properly, which could result in a buildup of stuck processes and lead to slowness in accessing the UCS Manager CLI and web UI. A sustained attack may result in a restart of internal UCS Manager processes and a temporary loss of access to the UCS Manager CLI and web UI. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucs-cli-dos-GQUxCnTe • CWE-400: Uncontrolled Resource Consumption CWE-664: Improper Control of a Resource Through its Lifetime •
CVE-2019-1734 – Cisco FXOS and NX-OS Software Sensitive File Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-1734
A vulnerability in the implementation of a CLI diagnostic command in Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to view sensitive system files that should be restricted. The attacker could use this information to conduct additional reconnaissance attacks. The vulnerability is due to incomplete role-based access control (RBAC) verification. An attacker could exploit this vulnerability by authenticating to the device and issuing a specific CLI diagnostic command with crafted user-input parameters. An exploit could allow the attacker to perform an arbitrary read of a file on the device, and the file may contain sensitive information. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-fxos-info • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-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 •
CVE-2019-1967 – Cisco NX-OS Software Network Time Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1967
A vulnerability in the Network Time Protocol (NTP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to excessive use of system resources when the affected device is logging a drop action for received MODE_PRIVATE (Mode 7) NTP packets. An attacker could exploit this vulnerability by flooding the device with a steady stream of Mode 7 NTP packets. A successful exploit could allow the attacker to cause high CPU and memory usage on the affected device, which could cause internal system processes to restart or cause the affected device to unexpectedly reload. Note: The NTP feature is enabled by default. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-nxos-ntp-dos • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
