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 •
CVSS: 8.6EPSS: 0%CPEs: 44EXPL: 0CVE-2020-3191 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software IPv6 DNS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3191
A vulnerability in DNS over IPv6 packet processing for Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to unexpectedly reload, resulting in a denial of service (DoS) condition. The vulnerability is due to improper length validation of a field in an IPv6 DNS packet. An attacker could exploit this vulnerability by sending a crafted DNS query over IPv6, which traverses the affected device. An exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. This vulnerability is specific to DNS over IPv6 traffic only. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-ipv6-67pA658k • CWE-20: Improper Input Validation •
CVSS: 9.1EPSS: 97%CPEs: 34EXPL: 7CVE-2020-3187 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Web Services Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2020-3187
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 conduct directory traversal attacks and obtain read and delete access to sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of the HTTP URL. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences. An exploit could allow the attacker to view or delete arbitrary files on the targeted system. When the device is reloaded after exploitation of this vulnerability, any files that were deleted are restored. • https://www.exploit-db.com/exploits/48723 https://github.com/CrackerCat/CVE-2020-3187 https://github.com/1337in/CVE-2020-3187 https://github.com/Cappricio-Securities/CVE-2020-3187 https://github.com/sujaygr8/CVE-2020-3187 https://github.com/sunyyer/CVE-2020-3187-Scanlist http://packetstormsecurity.com/files/158648/Cisco-Adaptive-Security-Appliance-Software-9.7-Arbitrary-File-Deletion.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-path-JE3azWw43 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.4EPSS: 0%CPEs: 8EXPL: 0CVE-2020-3334 – Cisco Firepower 2100 Series Security Appliances ARP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3334
A vulnerability in the ARP packet processing of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Security Appliances could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect processing of ARP packets received by the management interface of an affected device. An attacker could exploit this vulnerability by sending a series of unicast ARP packets in a short timeframe that would reach the management interface of an affected device. A successful exploit could allow the attacker to consume resources on an affected device, which would prevent the device from sending internal system keepalives and eventually cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el procesamiento de paquetes ARP del Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software para el Cisco Firepower 2100 Series Security Appliances, podría permitir a un atacante adyacente no autenticado causar que un dispositivo afectado se sobrecargue, resultando en una condición de denegación de servicio (DoS) sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fp2100-arp-dos-kLdCK8ks • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
