https://notcve.org/view.php?id=CVE-2019-12663
A vulnerability in the Cisco TrustSec (CTS) Protected Access Credential (PAC) provisioning module of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of attributes in RADIUS messages. An attacker could exploit this vulnerability by sending a malicious RADIUS message to an affected device while the device is in a specific state. Una vulnerabilidad en el módulo de aprovisionamiento Cisco TrustSec (CTS) Protected Access Credential (PAC) del software Cisco IOS XE, podría permitir a un atacante remoto no autenticado causar una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS).

https://notcve.org/view.php?id=CVE-2019-12649
A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device. Una vulnerabilidad en la funcionalidad de Comprobación de Imagen del Software Cisco IOS XE, podría permitir a un atacante local autenticado instalar y arrancar una imagen de software malicioso o ejecutar archivos binarios sin firmar en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-digsig-bypass • CWE-347: Improper Verification of Cryptographic Signature •
