CVSS: 7.4EPSS: 0%CPEs: 132EXPL: 0CVE-2020-3512 – Cisco IOS and IOS XE Software PROFINET Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3512
A vulnerability in the PROFINET handler for Link Layer Discovery Protocol (LLDP) messages of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a crash on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of LLDP messages in the PROFINET LLDP message handler. An attacker could exploit this vulnerability by sending a malicious LLDP message to an affected device. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en el manejador PROFINET para los mensajes Link Layer Discovery Protocol (LLDP) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar un bloqueo en un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-profinet-dos-65qYG3W5 • CWE-388: 7PK - Errors CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-3207
A vulnerability in the processing of boot options of specific Cisco IOS XE Software switches could allow an authenticated, local attacker with root shell access to the underlying operating system (OS) to conduct a command injection attack during device boot. This vulnerability is due to insufficient input validation checks while processing boot options. An attacker could exploit this vulnerability by modifying device boot options to execute attacker-provided code. A successful exploit may allow an attacker to bypass the Secure Boot process and execute malicious code on an affected device with root-level privileges. Una vulnerabilidad en el procesamiento de las opciones de arranque de los switches específicos de Cisco IOS XE Software, podría permitir a un atacante local autenticado con acceso de shell root al sistema operativo (SO) subyacente llevar a cabo un ataque de inyección de comando durante el arranque del dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ngwc-cmdinj-KEwWVWR • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
