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 •

https://notcve.org/view.php?id=CVE-2017-6632
A vulnerability in the logging configuration of Secure Sockets Layer (SSL) policies for Cisco FirePOWER System Software 5.3.0 through 6.2.2 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to high consumption of system resources. The vulnerability is due to the logging of certain TCP packets by the affected software. An attacker could exploit this vulnerability by sending a flood of crafted TCP packets to an affected device. A successful exploit could allow the attacker to cause a DoS condition. The success of an exploit is dependent on how an administrator has configured logging for SSL policies for a device. • http://www.securityfocus.com/bid/98523 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170517-fpwr • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
