CVSS: 7.4EPSS: 0%CPEs: 149EXPL: 0CVE-2020-3508 – Cisco IOS XE Software for Cisco ASR 1000 Series 20-Gbps Embedded Services Processor IP ARP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3508
A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload. Una vulnerabilidad en la funcionalidad de Address Resolution Protocol (ARP) de IP de Cisco IOS XE Software para Cisco ASR 1000 Series Aggregation Services Routers con un Embedded Services Processor (ESP) de 20-Gbps instalado, podría permitir a un atacante adyacente no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esp20-arp-dos-GvHVggqJ • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.4EPSS: 0%CPEs: 51EXPL: 0CVE-2020-3511 – Cisco IOS and IOS XE Software ISDN Q.931 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3511
A vulnerability in the ISDN subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient input validation when the ISDN Q.931 messages are processed. An attacker could exploit this vulnerability by sending a malicious ISDN Q.931 message to an affected device. A successful exploit could allow the attacker to cause the process to crash, resulting in a reload of the affected device.

CVSS: 8.4EPSS: 0%CPEs: 34EXPL: 0CVE-2019-1950 – Cisco IOS XE SD-WAN Software Default Credentials Vulnerability
https://notcve.org/view.php?id=CVE-2019-1950
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-cred-EVGSF259 • CWE-255: Credentials Management Errors CWE-1188: Initialization of a Resource with an Insecure Default •

CVSS: 8.6EPSS: 0%CPEs: 25EXPL: 0CVE-2019-12646 – Cisco IOS XE Software NAT Session Initiation Protocol Application Layer Gateway Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12646
A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of transient SIP packets on which NAT is performed on an affected device. An attacker could exploit this vulnerability by using UDP port 5060 to send crafted SIP packets through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
