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: 2%CPEs: 9EXPL: 0CVE-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 •
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: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-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 •
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 •
