CVSS: 5.3EPSS: 0%CPEs: 38EXPL: 0CVE-2020-3188 – Cisco Firepower Threat Defense Software Management Interface Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3188
A vulnerability in how Cisco Firepower Threat Defense (FTD) Software handles session timeouts for management connections could allow an unauthenticated, remote attacker to cause a buildup of remote management connections to an affected device, which could result in a denial of service (DoS) condition. The vulnerability exists because the default session timeout period for specific to-the-box remote management connections is too long. An attacker could exploit this vulnerability by sending a large and sustained number of crafted remote management connections to an affected device, resulting in a buildup of those connections over time. A successful exploit could allow the attacker to cause the remote management interface or Cisco Firepower Device Manager (FDM) to stop responding and cause other management functions to go offline, resulting in a DoS condition. The user traffic that is flowing through the device would not be affected, and the DoS condition would be isolated to remote management only. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-mgmt-interface-dos-FkG4MuTU • CWE-399: Resource Management Errors CWE-613: Insufficient Session Expiration •
CVSS: 8.6EPSS: 0%CPEs: 38EXPL: 0CVE-2020-3179 – Cisco Firepower Threat Defense Software Generic Routing Encapsulation Tunnel IPv6 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3179
A vulnerability in the generic routing encapsulation (GRE) tunnel decapsulation feature of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory handling error when GRE over IPv6 traffic is processed. An attacker could exploit this vulnerability by sending crafted GRE over IPv6 packets with either IPv4 or IPv6 payload through an affected device. A successful exploit could allow the attacker to cause the device to crash, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad de descapsulación de túnel generic routing encapsulation (GRE) del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-dos-2-sS2h7aWe • CWE-415: Double Free •
CVSS: 5.3EPSS: 0%CPEs: 39EXPL: 0CVE-2020-3186 – Cisco Firepower Threat Defense Software Management Access List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3186
A vulnerability in the management access list configuration of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured management interface access list on an affected system. The vulnerability is due to the configuration of different management access lists, with ports allowed in one access list and denied in another. An attacker could exploit this vulnerability by sending crafted remote management traffic to the local IP address of an affected system. A successful exploit could allow the attacker to bypass the configured management access list policies, and traffic to the management interface would not be properly denied. Una vulnerabilidad en la configuración de listas de acceso de administración del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado omitir una lista de acceso de la interfaz de administración configurada sobre un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-accesslist-bypass-5dZs5qZp • CWE-284: Improper Access Control •
CVSS: 8.6EPSS: 0%CPEs: 39EXPL: 0CVE-2019-15256 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software IKEv1 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-15256
A vulnerability in the Internet Key Exchange version 1 (IKEv1) feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper management of system memory. An attacker could exploit this vulnerability by sending malicious IKEv1 traffic to an affected device. The attacker does not need valid credentials to authenticate the VPN session, nor does the attacker's source address need to match a peer statement in the crypto map applied to the ingress interface of the affected device. An exploit could allow the attacker to exhaust system memory resources, leading to a reload of an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-ftd-ikev1-dos • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
