CVE-2020-3415 – Cisco NX-OS Software Data Management Engine Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-3415
A vulnerability in the Data Management Engine (DME) of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the Cisco Discovery Protocol process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-dme-rce-cbE3nhZS • CWE-787: Out-of-bounds Write •
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-2020-3170 – Cisco NX-OS Software NX-API Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3170
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 Cisco 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-20200226-nxos-api-dos • CWE-20: Improper Input Validation •
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-2019-1966 – Cisco Unified Computing System Fabric Interconnect root Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1966
A vulnerability in a specific CLI command within the local management (local-mgmt) context for Cisco UCS Fabric Interconnect Software could allow an authenticated, local attacker to gain elevated privileges as the root user on an affected device. The vulnerability is due to extraneous subcommand options present for a specific CLI command within the local-mgmt context. An attacker could exploit this vulnerability by authenticating to an affected device, entering the local-mgmt context, and issuing a specific CLI command and submitting user input. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device. The attacker would need to have valid user credentials for the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-ucs-privescalation • CWE-264: Permissions, Privileges, and Access Controls •
