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-2020-3409
A vulnerability in the PROFINET feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to crash and reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted PROFINET packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted PROFINET packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to crash and reload, resulting in a DoS condition on the device. Una vulnerabilidad en la funcionalidad PROFINET de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se bloquee y recargue, resultando en una condición de denegación de servicio (DoS) en el dispositivo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-profinet-J9QMCHPB • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.4EPSS: 0%CPEs: 132EXPL: 0CVE-2020-3512 – Cisco IOS and IOS XE Software PROFINET Link Layer Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3512
A vulnerability in the PROFINET handler for Link Layer Discovery Protocol (LLDP) messages of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a crash on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of LLDP messages in the PROFINET LLDP message handler. An attacker could exploit this vulnerability by sending a malicious LLDP message to an affected device. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en el manejador PROFINET para los mensajes Link Layer Discovery Protocol (LLDP) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante adyacente no autenticado causar un bloqueo en un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-profinet-dos-65qYG3W5 • CWE-388: 7PK - Errors CWE-400: Uncontrolled Resource Consumption •
