CVSS: 8.6EPSS: 0%CPEs: 322EXPL: 0CVE-2022-20919 – Cisco IOS and IOS XE Software Common Industrial Protocol Request Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20919
A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento de paquetes malformados del Protocolo Industrial Común (CIP) que se envían al software Cisco IOS y al software Cisco IOS XE podría permitir a un atacante remoto no autenticado causar una recarga no esperada del dispositivo afectado, lo que provocaría una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-cip-dos-9rTbKLt9 • CWE-248: Uncaught Exception CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.6EPSS: 0%CPEs: 364EXPL: 0CVE-2022-20848 – Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points UDP Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20848
A vulnerability in the UDP processing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to the improper processing of UDP datagrams. An attacker could exploit this vulnerability by sending malicious UDP datagrams to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad de procesamiento UDP del software Cisco IOS XE para controladores inalámbricos integrados en los puntos de acceso de la serie Catalyst 9100 podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wlc-udp-dos-XDyEwhNz • CWE-399: Resource Management Errors •
CVSS: 7.2EPSS: 0%CPEs: 62EXPL: 0CVE-2022-20677 – Cisco IOx Application Hosting Environment Vulnerabilities
https://notcve.org/view.php?id=CVE-2022-20677
Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Múltiples vulnerabilidades en el entorno de alojamiento de aplicaciones Cisco IOx en varias plataformas de Cisco podrían permitir a un atacante inyectar comandos arbitrarios en el sistema operativo del host subyacente, ejecutar código arbitrario en el sistema operativo del host subyacente, instalar aplicaciones sin estar autenticado o conducir un ataque de tipo cross-site scripting (XSS) contra un usuario del software afectado.

CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2022-20714 – Cisco IOS XR Software for ASR 9000 Series Routers Lightspeed-Plus Line Cards Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20714
A vulnerability in the data plane microcode of Lightspeed-Plus line cards for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause the line card to reset. This vulnerability is due to the incorrect handling of malformed packets that are received on the Lightspeed-Plus line cards. An attacker could exploit this vulnerability by sending a crafted IPv4 or IPv6 packet through an affected device. A successful exploit could allow the attacker to cause the Lightspeed-Plus line card to reset, resulting in a denial of service (DoS) condition for any traffic that traverses that line card. Una vulnerabilidad en el microcódigo del plano de datos de las tarjetas de línea Lightspeed-Plus para Cisco ASR 9000 Series Aggregation Services Routers podría permitir a un atacante remoto no autenticado causar el reinicio de la tarjeta de línea. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-lsplus-Z6AQEOjk • CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •
CVSS: 7.5EPSS: 0%CPEs: 48EXPL: 0CVE-2021-34737 – Cisco IOS XR Software DHCP Version 4 Server Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34737
A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition. This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the dhcpd process. While the dhcpd process is restarting, which may take up to approximately two minutes, DHCPv4 server services are unavailable on the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-dhcp-dos-pjPVReLU • CWE-476: NULL Pointer Dereference •
