CVSS: 7.7EPSS: 0%CPEs: 184EXPL: 0CVE-2019-1963 – Cisco FXOS and NX-OS Software Authenticated Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1963
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, remote attacker to cause the SNMP application on an affected device to restart unexpectedly. The vulnerability is due to improper validation of Abstract Syntax Notation One (ASN.1)-encoded variables in SNMP packets. An attacker could exploit this vulnerability by sending a crafted SNMP packet to the SNMP daemon on the affected device. A successful exploit could allow the attacker to cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. Una vulnerabilidad en el procesador de paquetes de entrada del Protocolo simple de administración de redes (SNMP) del software Cisco FXOS y del software Cisco NX-OS podría permitir que un atacante remoto autenticado haga que la aplicación SNMP en un dispositivo afectado se reinicie inesperadamente. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-fxnxos-snmp-dos • CWE-20: Improper Input Validation •

A vulnerability in the network-operator user role implementation for Cisco NX-OS System Software could allow an authenticated, local attacker to improperly delete valid user accounts. The network-operator role should not be able to delete other configured users on the device. The vulnerability is due to a lack of proper role-based access control (RBAC) checks for the actions that a user with the network-operator role is allowed to perform. An attacker could exploit this vulnerability by authenticating to the device with user credentials that give that user the network-operator role. Successful exploitation could allow the attacker to impact the integrity of the device by deleting configured user credentials. • http://www.securityfocus.com/bid/102750 http://www.securitytracker.com/id/1040248 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180117-nxos1 • CWE-264: Permissions, Privileges, and Access Controls CWE-862: Missing Authorization •
