https://notcve.org/view.php?id=CVE-2018-15388
A vulnerability in the WebVPN login process 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 existing WebVPN login operations. An attacker could exploit this vulnerability by sending multiple WebVPN login requests to the device. A successful exploit could allow the attacker to increase CPU load on the device, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el proceso de inicio de sesión (login) en la WebVPN de los software Adaptive Security Appliance (ASA) y Firepower Threat Defense (FTD) de Cisco, podría permitir que un atacante remoto no identificado cause un aumento en la utilización de la CPU en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-sd-cpu-dos • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.8EPSS: 0%CPEs: 1EXPL: 0CVE-2019-1691 – Cisco Firepower Threat Defense Software SSL or TLS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1691
A vulnerability in the detection engine of Cisco Firepower Threat Defense Software could allow an unauthenticated, remote attacker to cause the unexpected restart of the SNORT detection engine, resulting in a denial of service (DoS) condition. The vulnerability is due to the incomplete error handling of the SSL or TLS packet header during the connection establishment. An attacker could exploit this vulnerability by sending a crafted SSL or TLS packet during the connection handshake. An exploit could allow the attacker to cause the SNORT detection engine to unexpectedly restart, resulting in a partial DoS condition while the detection engine restarts. Versions prior to 6.2.3.4 are affected. • http://www.securityfocus.com/bid/107099 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190220-fpwr-ssltls-dos • CWE-20: Improper Input Validation CWE-755: Improper Handling of Exceptional Conditions •
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 •

https://notcve.org/view.php?id=CVE-2018-15454
A vulnerability in the Session Initiation Protocol (SIP) inspection engine of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload or trigger high CPU, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of SIP traffic. An attacker could exploit this vulnerability by sending SIP requests designed to specifically trigger this issue at a high rate across an affected device. Software updates that address this vulnerability are not yet available. Una vulnerabilidad en el motor de inspección SIP (Session Initiation Protocol) de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue o el alto uso de recursos de la CPU, lo que resulta en una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105768 http://www.securitytracker.com/id/1042129 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181031-asaftd-sip-dos • CWE-20: Improper Input Validation •
CVSS: 7.1EPSS: 0%CPEs: 1EXPL: 0CVE-2018-15390 – Cisco Firepower Threat Defense Software FTP Inspection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15390
A vulnerability in the FTP inspection engine of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software fails to release spinlocks when a device is running low on system memory, if the software is configured to apply FTP inspection and an access control rule to transit traffic, and the access control rule is associated with an FTP file policy. An attacker could exploit this vulnerability by sending a high rate of transit traffic through an affected device to cause a low-memory condition on the device. A successful exploit could allow the attacker to cause a software panic on the affected device, which could cause the device to reload and result in a temporary DoS condition. Una vulnerabilidad en el motor de inspección FTP de Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto sin autenticar haga que el dispositivo afectado se reinicie, provocando una denegación de servicio (DoS) en consecuencia. • http://www.securityfocus.com/bid/105519 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-ftd-inspect-dos • CWE-399: Resource Management Errors CWE-667: Improper Locking •
