CVSS: 5.8EPSS: 0%CPEs: 1EXPL: 0CVE-2020-3285 – Cisco Firepower Threat Defense Software SSL/TLS URL Category Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3285
A vulnerability in the Transport Layer Security version 1.3 (TLS 1.3) policy with URL category functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured TLS 1.3 policy to block traffic for a specific URL. The vulnerability is due to a logic error with Snort handling of the connection with the TLS 1.3 policy and URL category configuration. An attacker could exploit this vulnerability by sending crafted TLS 1.3 connections to an affected device. A successful exploit could allow the attacker to bypass the TLS 1.3 policy and access URLs that are outside the affected device and normally would be dropped. Una vulnerabilidad en la política Transport Layer Security versión 1.3 (TLS 1.3) con funcionalidad URL category para el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado omitir una política TLS versión 1.3 configurada para bloquear el tráfico de una URL específica. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssl-bypass-O5tGum2n • CWE-693: Protection Mechanism Failure •
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 •

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 •
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 •

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 •
