CVSS: 8.6EPSS: 0%CPEs: 62EXPL: 0CVE-2022-20682 – Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family CAPWAP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20682
A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to inadequate input validation of incoming CAPWAP packets encapsulating multicast DNS (mDNS) queries. An attacker could exploit this vulnerability by connecting to a wireless network and sending a crafted mDNS query, which would flow through and be processed by the wireless controller. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition. Una vulnerabilidad en el procesamiento del protocolo de control y aprovisionamiento de puntos de acceso inalámbricos (CAPWAP) de Cisco IOS XE Wireless Controller Software for the Catalyst 9000 Family podría 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-c9800-capwap-mdns-6PSn7gKU • CWE-476: NULL Pointer Dereference CWE-690: Unchecked Return Value to NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-20683
A vulnerability in the Application Visibility and Control (AVC-FNF) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient packet verification for traffic inspected by the AVC feature. An attacker could exploit this vulnerability by sending crafted packets from the wired network to a wireless client, resulting in the crafted packets being processed by the wireless controller. A successful exploit could allow the attacker to cause a crash and reload of the affected device, resulting in a DoS condition.

CVSS: 7.7EPSS: 0%CPEs: 127EXPL: 0CVE-2022-20692 – Cisco IOS XE Software NETCONF Over SSH Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20692
A vulnerability in the NETCONF over SSH feature of Cisco IOS XE Software could allow a low-privileged, authenticated, remote attacker to cause a denial of service condition (DoS) on an affected device. This vulnerability is due to insufficient resource management. An attacker could exploit this vulnerability by initiating a large number of NETCONF over SSH connections. A successful exploit could allow the attacker to exhaust resources, causing the device to reload and resulting in a DoS condition on an affected device. Una vulnerabilidad en la función NETCONF sobre SSH del software Cisco IOS XE podría permitir a un atacante remoto con pocos privilegios y autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ncossh-dos-ZAkfOdq8 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-20693
A vulnerability in the web UI feature of Cisco IOS XE Software could allow an authenticated, remote attacker to perform an injection attack against an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web UI API. A successful exploit could allow the attacker to inject commands to the underlying operating system with root privileges. Una vulnerabilidad en la funcionalidad de la Interfaz de Usuario web del software Cisco IOS XE podría permitir a un atacante remoto autenticado llevar a cabo un ataque de inyección contra un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webuiapi-inj-Nyrq92Od • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 7.1EPSS: 0%CPEs: 234EXPL: 0CVE-2022-20694 – Cisco IOS XE Software Border Gateway Protocol Resource Public Key Infrastructure Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20694
A vulnerability in the implementation of the Resource Public Key Infrastructure (RPKI) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the Border Gateway Protocol (BGP) process to crash, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of a specific RPKI to Router (RTR) Protocol packet header. An attacker could exploit this vulnerability by compromising the RPKI validator server and sending a specifically crafted RTR packet to an affected device. Alternatively, the attacker could use man-in-the-middle techniques to impersonate the RPKI validator server and send a crafted RTR response packet over the established RTR TCP connection to the affected device. A successful exploit could allow the attacker to cause a DoS condition because the BGP process could constantly restart and BGP routing could become unstable. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-rpki-dos-2EgCNeKE • CWE-617: Reachable Assertion •
