CVSS: 6.5EPSS: 0%CPEs: 9EXPL: 0CVE-2019-1695 – Cisco Adaptive Security Appliance and Firepower Threat Defense Software Layer 2 Filtering Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1695
A vulnerability in the detection engine of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, adjacent attacker to send data directly to the kernel of an affected device. The vulnerability exists because the software improperly filters Ethernet frames sent to an affected device. An attacker could exploit this vulnerability by sending crafted packets to the management interface of an affected device. A successful exploit could allow the attacker to bypass the Layer 2 (L2) filters and send data directly to the kernel of the affected device. A malicious frame successfully delivered would make the target device generate a specific syslog entry. • http://www.securityfocus.com/bid/108173 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftd-bypass • CWE-284: Improper Access Control •
CVSS: 7.7EPSS: 0%CPEs: 19EXPL: 0CVE-2019-1693 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software WebVPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1693
A vulnerability in the WebVPN service of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper management of authenticated sessions in the WebVPN portal. An attacker could exploit this vulnerability by authenticating with valid credentials and accessing a specific URL in the WebVPN portal. A successful exploit could allow the attacker to cause the device to reload, resulting in a temporary DoS condition. Una vulnerabilidad en el servicio WebVPN del software Cisco Adaptive Security Appliance (ASA) y del software Cisco Firepower Threat Defense (FTD) podía permitir a un atacante remoto, no autenticado, causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/108157 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftd-dos • CWE-399: Resource Management Errors •
CVSS: 7.8EPSS: 0%CPEs: 19EXPL: 0CVE-2019-1687 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software TCP Proxy Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1687
A vulnerability in the TCP proxy functionality for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to an error in TCP-based packet inspection, which could cause the TCP packet to have an invalid Layer 2 (L2)-formatted header. An attacker could exploit this vulnerability by sending a crafted TCP packet sequence to the targeted device. A successful exploit could allow the attacker to cause a DoS condition. Una vulnerabilidad en la funcionalidad de proxy TCP para el software Adaptive Security Appliance (ASA) de Cisco y el software Firepower Threat Defense (FTD) de Cisco, podría permitir que un atacante remoto no identificado cause que el dispositivo se reinicie inesperadamente, dando como resultado una condición de Denegación de Servicio (DoS) . • http://www.securityfocus.com/bid/108176 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftdtcp-dos • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-15462 – Cisco Firepower Threat Defense Software TCP Ingress Handler Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15462
A vulnerability in the TCP ingress handler for the data interfaces that are configured with management access to Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an increase in CPU and memory usage, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient ingress TCP rate limiting for TCP ports 22 (SSH) and 443 (HTTPS). An attacker could exploit this vulnerability by sending a crafted, steady stream of TCP traffic to port 22 or 443 on the data interfaces that are configured with management access to the affected device. Una vulnerabilidad en el controlador de ingreso de TCP para las interfaces de datos que están configuradas con acceso de administración al programa Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado provoque un aumento en el uso de la CPU y la memoria, dando como resultado una denegación de servicio( DoS) condición. La vulnerabilidad se debe a una limitación de la tasa de TCP de ingreso insuficiente para los puertos TCP 22 (SSH) y 443 (HTTPS). • http://www.securityfocus.com/bid/108178 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-firepower-dos • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1669 – Cisco Firepower Threat Defense Software Packet Inspection and Enforcement Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1669
A vulnerability in the data acquisition (DAQ) component of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured access control policies or cause a denial of service (DoS) condition. The vulnerability exists because the affected software improperly manages system memory resources when inspecting traffic. An attacker could exploit this vulnerability by generating specific traffic patterns for the software to inspect. A successful exploit could allow the attacker to exhaust system memory resources used for traffic inspection. Depending on the configuration, the FTD Software could fail open and cease to inspect traffic or fail closed and result in a DoS condition. • http://www.securityfocus.com/bid/106721 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190123-firepowertds-bypass • CWE-693: Protection Mechanism Failure •
