CVSS: 6.7EPSS: 0%CPEs: 28EXPL: 0CVE-2020-3458 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software for Firepower 1000/2100 Series Appliances Secure Boot Bypass Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3458
Multiple vulnerabilities in the secure boot process of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software for the Firepower 1000 Series and Firepower 2100 Series Appliances could allow an authenticated, local attacker to bypass the secure boot mechanism. The vulnerabilities are due to insufficient protections of the secure boot process. An attacker could exploit these vulnerabilities by injecting code into specific files that are then referenced during the device boot process. A successful exploit could allow the attacker to break the chain of trust and inject code into the boot process of the device, which would be executed at each boot and maintain persistence across reboots. Múltiples vulnerabilidades en el proceso de inicio seguro de Cisco Adaptive Security Appliance (ASA) Software y Firepower Threat Defense (FTD) Software para Dispositivos Firepower 1000 Series y Firepower 2100 Series podrían permitir a un atacante local autenticado omitir el mecanismo de inicio seguro. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fxos-sbbyp-KqP6NgrE • CWE-693: Protection Mechanism Failure •
CVSS: 8.2EPSS: 0%CPEs: 5EXPL: 0CVE-2020-3514 – Cisco Firepower Threat Defense Software Multi-Instance Container Escape Vulnerability
https://notcve.org/view.php?id=CVE-2020-3514
A vulnerability in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their Cisco FTD instance and execute commands with root privileges in the host namespace. The attacker must have valid credentials on the device.The vulnerability exists because a configuration file that is used at container startup has insufficient protections. An attacker could exploit this vulnerability by modifying a specific container configuration file on the underlying file system. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running Cisco FTD instances or the host Cisco FXOS device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-container-esc-FmYqFBQV • CWE-216: DEPRECATED: Containment Errors (Container Errors) •
CVSS: 8.6EPSS: 0%CPEs: 11EXPL: 0CVE-2020-3528 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software OSPFv2 Link-Local Signaling Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3528
A vulnerability in the OSPF Version 2 (OSPFv2) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete input validation when the affected software processes certain OSPFv2 packets with Link-Local Signaling (LLS) data. An attacker could exploit this vulnerability by sending a malformed OSPFv2 packet to an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition. Una vulnerabilidad en la implementación OSPF versión 2 (OSPFv2) de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-ospflls-37Xy2q6r • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.6EPSS: 0%CPEs: 11EXPL: 0CVE-2020-3529 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SSL VPN Direct Memory Access Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3529
A vulnerability in the SSL VPN negotiation process for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient direct memory access (DMA) memory management during the negotiation phase of an SSL VPN connection. An attacker could exploit this vulnerability by sending a steady stream of crafted Datagram TLS (DTLS) traffic to an affected device. A successful exploit could allow the attacker to exhaust DMA memory on the device and cause a DoS condition. Una vulnerabilidad en el proceso de negociación de SSL VPN para Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-sslvpndma-dos-HRrqB9Yx • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.6EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3533 – Cisco Firepower Threat Defense Software SNMP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3533
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly. The vulnerability is due to a lack of sufficient memory management protections under heavy SNMP polling loads. An attacker could exploit this vulnerability by sending a high rate of SNMP requests to the SNMP daemon through the management interface on an affected device. A successful exploit could allow the attacker to cause the SNMP daemon process to consume a large amount of system memory over time, which could then lead to an unexpected device restart, causing a denial of service (DoS) condition. This vulnerability affects all versions of SNMP. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-snmp-dos-R8ENPbOs • CWE-400: Uncontrolled Resource Consumption •
