CVSS: 9.8EPSS: 1%CPEs: 29EXPL: 0CVE-2020-3125 – Cisco Adaptive Security Appliance Software Kerberos Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3125
A vulnerability in the Kerberos authentication feature of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to impersonate the Kerberos key distribution center (KDC) and bypass authentication on an affected device that is configured to perform Kerberos authentication for VPN or local device access. The vulnerability is due to insufficient identity verification of the KDC when a successful authentication response is received. An attacker could exploit this vulnerability by spoofing the KDC server response to the ASA device. This malicious response would not have been authenticated by the KDC. A successful attack could allow an attacker to bypass Kerberos authentication. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-asa-kerberos-bypass-96Gghe2sS • CWE-287: Improper Authentication •
CVSS: 8.6EPSS: 0%CPEs: 38EXPL: 0CVE-2020-3179 – Cisco Firepower Threat Defense Software Generic Routing Encapsulation Tunnel IPv6 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3179
A vulnerability in the generic routing encapsulation (GRE) tunnel decapsulation feature 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 a memory handling error when GRE over IPv6 traffic is processed. An attacker could exploit this vulnerability by sending crafted GRE over IPv6 packets with either IPv4 or IPv6 payload through an affected device. A successful exploit could allow the attacker to cause the device to crash, resulting in a DoS condition. Una vulnerabilidad en la funcionalidad de descapsulación de túnel generic routing encapsulation (GRE) del Cisco Firepower Threat Defense (FTD) Software, podría 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-ftd-dos-2-sS2h7aWe • CWE-415: Double Free •
CVSS: 5.3EPSS: 0%CPEs: 39EXPL: 0CVE-2020-3186 – Cisco Firepower Threat Defense Software Management Access List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3186
A vulnerability in the management access list configuration of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured management interface access list on an affected system. The vulnerability is due to the configuration of different management access lists, with ports allowed in one access list and denied in another. An attacker could exploit this vulnerability by sending crafted remote management traffic to the local IP address of an affected system. A successful exploit could allow the attacker to bypass the configured management access list policies, and traffic to the management interface would not be properly denied. Una vulnerabilidad en la configuración de listas de acceso de administración del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado omitir una lista de acceso de la interfaz de administración configurada sobre un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-accesslist-bypass-5dZs5qZp • CWE-284: Improper Access Control •
CVSS: 7.5EPSS: 0%CPEs: 24EXPL: 0CVE-2011-2054 – Cisco ASA Secondary Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2011-2054
A vulnerability in the Cisco ASA that could allow a remote attacker to successfully authenticate using the Cisco AnyConnect VPN client if the Secondary Authentication type is LDAP and the password is left blank, providing the primary credentials are correct. The vulnerabilities is due to improper input validation of certain parameters passed to the affected software. An attacker must have the correct primary credentials in order to successfully exploit this vulnerability. Una vulnerabilidad en el Cisco ASA , podría permitir a atacantes remotos una autenticación con éxito usando el cliente Cisco AnyConnect VPN si el tipo Secondary Authentication es LDAP y la contraseña se deja en blanco, siempre que las credenciales principales sean correctas. Estas vulnerabilidades son debido a una comprobación de entrada inapropiada de determinados parámetros pasados ?? • https://quickview.cloudapps.cisco.com/quickview/bug/CSCtq58884 • CWE-287: Improper Authentication •
CVSS: 7.8EPSS: 0%CPEs: 19EXPL: 0CVE-2019-12698 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software WebVPN CPU Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12698
A vulnerability in the WebVPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause increased CPU utilization on an affected device. The vulnerability is due to excessive processing load for a specific WebVPN HTTP page request. An attacker could exploit this vulnerability by sending multiple WebVPN HTTP page load requests for a specific URL. A successful exploit could allow the attacker to increase CPU load on the device, resulting in a denial of service (DoS) condition, which could cause traffic to be delayed through the device. Una vulnerabilidad en la funcionalidad WebVPN del Software Cisco Adaptive Security Appliance (ASA) y el Software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto no autenticado causar una mayor utilización de la CPU en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-ftd-dos • CWE-400: Uncontrolled Resource Consumption •
