CVE-2020-3298 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Malformed OSPF Packets Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3298
A vulnerability in the Open Shortest Path First (OSPF) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper memory protection mechanisms while processing certain OSPF packets. An attacker could exploit this vulnerability by sending a series of malformed OSPF packets in a short period of time to an affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition for client traffic that is traversing the device. Una vulnerabilidad en la implementación de Open Shortest Path First (OSPF) del Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar el reinicio de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ftd-ospf-dos-RhMQY8qx • CWE-125: Out-of-bounds Read •
CVE-2020-3259 – Cisco ASA and FTD Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-3259
A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to retrieve memory contents on an affected device, which could lead to the disclosure of confidential information. The vulnerability is due to a buffer tracking issue when the software parses invalid URLs that are requested from the web services interface. An attacker could exploit this vulnerability by sending a crafted GET request to the web services interface. A successful exploit could allow the attacker to retrieve memory contents, which could lead to the disclosure of confidential information. Note: This vulnerability affects only specific AnyConnect and WebVPN configurations. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-info-disclose-9eJtycMB • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2020-3253 – Cisco Firepower Threat Defense Software Shell Access Vulnerability
https://notcve.org/view.php?id=CVE-2020-3253
A vulnerability in the support tunnel feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to access the shell of an affected device even though expert mode is disabled. The vulnerability is due to improper configuration of the support tunnel feature. An attacker could exploit this vulnerability by enabling the support tunnel, setting a key, and deriving the tunnel password. A successful exploit could allow the attacker to run any system command with root access on an affected device. Una vulnerabilidad en la funcionalidad support tunnel del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante local autenticado acceder al shell de un dispositivo afectado aunque el modo expert esté desactivado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-shell-9rhJF68K • CWE-284: Improper Access Control •
CVE-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 •
CVE-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 •
