CVSS: 8.6EPSS: 0%CPEs: 41EXPL: 0CVE-2020-3283 – Cisco Firepower 1000 Series SSL/TLS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3283
A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Firepower Threat Defense (FTD) Software when running on the Cisco Firepower 1000 Series platform could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to a communication error between internal functions. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message to an affected device. A successful exploit could allow the attacker to cause a buffer underrun, which leads to a crash. The crash causes the affected device to reload. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-tls-dos-4v5nmWtZ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 27EXPL: 0CVE-2020-3255 – Cisco Firepower Threat Defense Software Packet Flood Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3255
A vulnerability in the packet processing functionality 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 inefficient memory management. An attacker could exploit this vulnerability by sending a high rate of IPv4 or IPv6 traffic through an affected device. This traffic would need to match a configured block action in an access control policy. An exploit could allow the attacker to cause a memory exhaustion condition on the affected device, which would result in a DoS for traffic transiting the device, as well as sluggish performance of the management interface. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-dos-N2vQZASR • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.6EPSS: 0%CPEs: 32EXPL: 0CVE-2020-3254 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Media Gateway Control Protocol Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3254
Multiple vulnerabilities in the Media Gateway Control Protocol (MGCP) inspection feature of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerabilities are due to inefficient memory management. An attacker could exploit these vulnerabilities by sending crafted MGCP packets through an affected device. An exploit could allow the attacker to cause memory exhaustion resulting in a restart of an affected device, causing a DoS condition for traffic traversing the device. Múltiples vulnerabilidades en la funcionalidad de inspección de Media Gateway Control Protocol (MGCP) del Cisco Adaptive Security Appliance (ASA) Software y el Firepower Threat Defense (FTD) Software, podrían 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-asaftd-mgcp-SUqB8VKH • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.6EPSS: 0%CPEs: 58EXPL: 0CVE-2020-3196 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SSL/TLS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3196
A vulnerability in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust memory resources on the affected device, leading to a denial of service (DoS) condition. The vulnerability is due to improper resource management for inbound SSL/TLS connections. An attacker could exploit this vulnerability by establishing multiple SSL/TLS connections with specific conditions to the affected device. A successful exploit could allow the attacker to exhaust the memory on the affected device, causing the device to stop accepting new SSL/TLS connections and resulting in a DoS condition for services on the device that process SSL/TLS traffic. Manual intervention is required to recover an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ssl-vpn-dos-qY7BHpjN • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.6EPSS: 0%CPEs: 28EXPL: 0CVE-2020-3195 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software OSPF Packets Processing Memory Leak Vulnerability
https://notcve.org/view.php?id=CVE-2020-3195
A vulnerability in the Open Shortest Path First (OSPF) implementation in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to incorrect processing of certain OSPF packets. An attacker could exploit this vulnerability by sending a series of crafted OSPF packets to be processed by an affected device. A successful exploit could allow the attacker to continuously consume memory on an affected device and eventually cause it to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la implementación de Open Shortest Path First (OSPF) en el Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una pérdida de memoria sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-ospf-memleak-DHpsgfnv • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
