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 •

https://notcve.org/view.php?id=CVE-2019-15992
A vulnerability in the implementation of the Lua interpreter integrated in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying Linux operating system of an affected device. The vulnerability is due to insufficient restrictions on the allowed Lua function calls within the context of user-supplied Lua scripts. A successful exploit could allow the attacker to trigger a heap overflow condition and execute arbitrary code with root privileges on the underlying Linux operating system of an affected device. Una vulnerabilidad en la implementación del intérprete Lua integrado en Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto autenticado ejecutar código arbitrario con privilegios root en el sistema operativo Linux subyacente de un dispositivo afectado. La vulnerabilidad es debido a restricciones insuficientes en las llamadas a funciones Lua permitidas dentro del contexto de los scripts Lua suministrados por el usuario. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191112-asa-ftd-lua-rce • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-0228
A vulnerability in the ingress flow creation functionality of Cisco Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause the CPU to increase upwards of 100% utilization, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to incorrect handling of an internal software lock that could prevent other system processes from getting CPU cycles, causing a high CPU condition. An attacker could exploit this vulnerability by sending a steady stream of malicious IP packets that can cause connections to be created on the targeted device. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition during which traffic through the device could be delayed. This vulnerability applies to either IPv4 or IPv6 ingress traffic. • http://www.securityfocus.com/bid/104220 http://www.securitytracker.com/id/1040724 https://ics-cert.us-cert.gov/advisories/ICSA-18-184-01 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-asa2 • CWE-20: Improper Input Validation CWE-667: Improper Locking •

https://notcve.org/view.php?id=CVE-2018-0231
A vulnerability in the Transport Layer Security (TLS) library 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 the affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious TLS message to an interface enabled for Secure Layer Socket (SSL) services on an affected device. Messages using SSL Version 3 (SSLv3) or SSL Version 2 (SSLv2) cannot be be used to exploit this vulnerability. An exploit could allow the attacker to cause a buffer underflow, triggering a crash on an affected device. • http://www.securitytracker.com/id/1040725 https://ics-cert.us-cert.gov/advisories/ICSA-18-184-01 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-asa3 • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •
