CVSS: 8.6EPSS: 0%CPEs: 10EXPL: 0CVE-2020-3566 – Cisco IOS XR Software DVMRP Memory Exhaustion Vulnerability
https://notcve.org/view.php?id=CVE-2020-3566
A vulnerability in the Distance Vector Multicast Routing Protocol (DVMRP) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to exhaust process memory of an affected device. The vulnerability is due to insufficient queue management for Internet Group Management Protocol (IGMP) packets. An attacker could exploit this vulnerability by sending crafted IGMP traffic to an affected device. A successful exploit could allow the attacker to cause memory exhaustion, resulting in instability of other processes. These processes may include, but are not limited to, interior and exterior routing protocols. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-dvmrp-memexh-dSmpdvfz • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 4.3EPSS: 0%CPEs: 3EXPL: 0CVE-2020-3449 – Cisco IOS XR Software Additional Paths Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3449
A vulnerability in the Border Gateway Protocol (BGP) additional paths feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to prevent authorized users from monitoring the BGP status and cause the BGP process to stop processing new updates, resulting in a denial of service (DOS) condition. The vulnerability is due to an incorrect calculation of lexicographical order when displaying additional path information within Cisco IOS XR Software, which causes an infinite loop. An attacker could exploit this vulnerability by sending a specific BGP update from a BGP neighbor peer session of an affected device; an authorized user must then issue a show bgp command for the vulnerability to be exploited. A successful exploit could allow the attacker to prevent authorized users from properly monitoring the BGP status and prevent BGP from processing new updates, resulting in outdated information in the routing and forwarding tables. Una vulnerabilidad en la funcionalidad de rutas adicionales del Border Gateway Protocol (BGP) del Cisco IOS XR Software podría permitir a un atacante remoto no autenticado impedir que los usuarios autorizados monitoreen el estado de BGP y causar que el proceso de BGP deje de procesar nuevas actualizaciones, resultando en una condición de servicio (DOS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-bgp-ErKEqAer • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 10.0EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3375 – Cisco SD-WAN Solution Software Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2020-3375
A vulnerability in Cisco SD-WAN Solution Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to information that they are not authorized to access, make changes to the system that they are not authorized to make, and execute commands on an affected system with privileges of the root user. Una vulnerabilidad en Cisco SD-WAN Solution Software podría permitir a un atacante remoto no autenticado causar un desbordamiento del búfer sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdbufof-h5f5VSeL • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 0CVE-2020-3364 – Cisco IOS XR Software Standby Route Processor Gigabit Ethernet Management Interface Access Control List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3364
A vulnerability in the access control list (ACL) functionality of the standby route processor management interface of Cisco IOS XR Software could allow an unauthenticated, remote attacker to reach the configured IP addresses on the standby route processor management Gigabit Ethernet Management interface. The vulnerability is due to a logic error that was introduced in the Cisco IOS XR Software, which prevents the ACL from working when applied against the standby route processor management interface. An attacker could exploit this vulnerability by attempting to access the device through the standby route processor management interface. Una vulnerabilidad en la funcionalidad Access Control List (ACL) de la interfaz de administración del procesador de ruta en espera de Cisco IOS XR Software, podría permitir a un atacante remoto no autenticado alcance las direcciones IP configuradas en la interfaz Gigabit Ethernet Management de administración del procesador de ruta en espera. La vulnerabilidad es debido a un error lógico que se introdujo en el Cisco IOS XR Software, que impide que la ACL funcione cuando se aplica contra la interfaz de administración del procesador de ruta en espera. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xracl-zbWSWREt • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
