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: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0467 – Cisco IOS and IOS XE Software IPv6 Hop-by-Hop Options Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0467
A vulnerability in the IPv6 processing code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect handling of specific IPv6 hop-by-hop options. An attacker could exploit this vulnerability by sending a malicious IPv6 packet to or through the affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. Una vulnerabilidad en el código de procesamiento IPv6 en Cisco IOS y Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar haga que el dispositivo se reinicie. • http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ipv6hbh • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-0165
A vulnerability in the Internet Group Management Protocol (IGMP) packet-processing functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust buffers on an affected device, resulting in a denial of service (DoS) condition, aka a Memory Leak. The vulnerability is due to the affected software insufficiently processing IGMP Membership Query packets that are sent to an affected device. An attacker could exploit this vulnerability by sending a large number of IGMP Membership Query packets, which contain certain values, to an affected device. A successful exploit could allow the attacker to exhaust buffers on the affected device, resulting in a DoS condition that requires the device to be reloaded manually. This vulnerability affects: Cisco Catalyst 4500 Switches with Supervisor Engine 8-E, if they are running Cisco IOS XE Software Release 3.x.x.E and IP multicast routing is configured; Cisco devices that are running Cisco IOS XE Software Release 16.x, if IP multicast routing is configured. • http://www.securityfocus.com/bid/103568 http://www.securitytracker.com/id/1040592 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-igmp • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 8.6EPSS: 1%CPEs: 24EXPL: 0CVE-2018-0173 – Cisco IOS and IOS XE Software Improper Input Validation Vulnerability
https://notcve.org/view.php?id=CVE-2018-0173
A vulnerability in the Cisco IOS Software and Cisco IOS XE Software function that restores encapsulated option 82 information in DHCP Version 4 (DHCPv4) packets could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a Relay Reply denial of service (DoS) condition. The vulnerability exists because the affected software performs incomplete input validation of encapsulated option 82 information that it receives in DHCPOFFER messages from DHCPv4 servers. An attacker could exploit this vulnerability by sending a crafted DHCPv4 packet to an affected device, which the device would then forward to a DHCPv4 server. When the affected software processes the option 82 information that is encapsulated in the response from the server, an error could occur. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. • http://www.securityfocus.com/bid/103545 http://www.securitytracker.com/id/1040591 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-04 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-05 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-dhcpr2 https://www.tenable.com/security/research/tra-2018-06 • CWE-20: Improper Input Validation •

The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in Cisco IOS XE 2.1 through 3.17S, IOS XR 2.0.0 through 5.3.2, and NX-OS allows remote attackers to cause a denial of service (packet-processing outage) via crafted ND messages, aka Bug ID CSCuz66542, as exploited in the wild in May 2016. El protocolo de implementación Neighbor Discovery (ND) en la pila IPv6 en Cisco IOS XE 2.1 hasta la versión 3.17S, IOS XR 2.0.0 hasta la versión 5.3.2 y NX-OS permite a atacantes remotos provocar una denegación de servicio (interrupción de procesado de paquetes) a través de mensajes ND manipulados, también conocido como Bug ID CSCuz66542, tal como se ha explotado activamente en mayo de 2016. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160525-ipv6 http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20160824-01-ipv6-en http://www.securityfocus.com/bid/90872 http://www.securitytracker.com/id/1035962 http://www.securitytracker.com/id/1035963 http://www.securitytracker.com/id/1035964 http://www.securitytracker.com/id/1035965 http://www.securitytracker.com/id/1036651 • CWE-20: Improper Input Validation •
