https://notcve.org/view.php?id=CVE-2023-20227
A vulnerability in the Layer 2 Tunneling Protocol (L2TP) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain L2TP packets. An attacker could exploit this vulnerability by sending crafted L2TP packets to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. Una vulnerabilidad en la función Layer 2 Tunneling Protocol (L2TP) del software Cisco IOS XE podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe al manejo inadecuado de ciertos paquetes L2TP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-l2tp-dos-eB5tuFmV • CWE-388: 7PK - Errors •

https://notcve.org/view.php?id=CVE-2023-20226
A vulnerability in Application Quality of Experience (AppQoE) and Unified Threat Defense (UTD) on Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to the mishandling of a crafted packet stream through the AppQoE or UTD application. An attacker could exploit this vulnerability by sending a crafted packet stream through 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 Application Quality of Experience (AppQoE) y en el Unified Threat Defense (UTD) en el software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe al mal manejo de un flujo de paquetes manipulado a través de la aplicación AppQoE o UTD. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-appqoe-utd-dos-p8O57p5y • CWE-456: Missing Initialization of a Variable •
CVSS: 6.8EPSS: 0%CPEs: 621EXPL: 0CVE-2023-20081 – Cisco Adaptive Security Appliance Software, Firepower Threat Defense Software, IOS Software, and IOS XE Software IPv6 DHCP (DHCPv6) Client Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-20081
A vulnerability in the IPv6 DHCP (DHCPv6) client module of Cisco Adaptive Security Appliance (ASA) Software, Cisco Firepower Threat Defense (FTD) Software, Cisco IOS Software, and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient validation of DHCPv6 messages. An attacker could exploit this vulnerability by sending crafted DHCPv6 messages to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Note: To successfully exploit this vulnerability, the attacker would need to either control the DHCPv6 server or be in a man-in-the-middle position. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftdios-dhcpv6-cli-Zf3zTv • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-20818
Multiple vulnerabilities in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain elevated privileges. These vulnerabilities are due to improper access controls on commands within the application CLI. An attacker could exploit these vulnerabilities by running a malicious command on the application CLI. A successful exploit could allow the attacker to execute arbitrary commands as the root user.
