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: 6.5EPSS: 0%CPEs: 11EXPL: 0CVE-2022-20810 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family SNMP Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-20810
A vulnerability in the Simple Network Management Protocol (SNMP) of Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family could allow an authenticated, remote attacker to access sensitive information. This vulnerability is due to insufficient restrictions that allow a sensitive configuration detail to be disclosed. An attacker could exploit this vulnerability by retrieving data through SNMP read-only community access. A successful exploit could allow the attacker to view Service Set Identifier (SSID) preshared keys (PSKs) that are configured on the affected device. Una vulnerabilidad en el Protocolo simple de administración de redes (SNMP) del software Cisco IOS XE Wireless Controller para la familia Catalyst 9000 podría permitir a un atacante remoto autenticado acceder a información confidencial. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cwlc-snmpidv-rnyyQzUZ • CWE-202: Exposure of Sensitive Information Through Data Queries •
CVSS: 7.7EPSS: 0%CPEs: 965EXPL: 0CVE-2021-1620 – Cisco IOS and IOS XE Software IKEv2 AutoReconnect Feature Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1620
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition. Una vulnerabilidad en el soporte de Intercambio de Claves de Internet Versión 2 (IKEv2) para la funcionalidad AutoReconnect de Cisco IOS Software y Cisco IOS XE Software podría permitir a un atacante remoto autenticado agotar las direcciones IP libres del pool local asignado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev2-ebFrwMPr • CWE-563: Assignment to Variable without Use CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2021-1565
Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition. Varias vulnerabilidades en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9000 Family Wireless Controllers podrían permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-capwap-dos-gmNjdKOY • CWE-415: Double Free •

https://notcve.org/view.php?id=CVE-2021-34770
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a logic error that occurs during the validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a crafted CAPWAP packet to an affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the affected device to crash and reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento del protocolo Control and Provisioning of Wireless Access Points (CAPWAP) de Cisco IOS XE Software para Cisco Catalyst 9000 Family Wireless Controllers podría permitir a un atacante remoto no autenticado ejecutar código arbitrario con privilegios administrativos o causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-capwap-rce-LYgj8Kf • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
