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 •

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: 8.2EPSS: 0%CPEs: 7EXPL: 0CVE-2018-0453 – Cisco Firepower Management Center and Firepower System Software Sourcefire Tunnel Control Channel Command Execution Vulnerability
https://notcve.org/view.php?id=CVE-2018-0453
A vulnerability in the Sourcefire tunnel control channel protocol in Cisco Firepower System Software running on Cisco Firepower Threat Defense (FTD) sensors could allow an authenticated, local attacker to execute specific CLI commands with root privileges on the Cisco Firepower Management Center (FMC), or through Cisco FMC on other Firepower sensors and devices that are controlled by the same Cisco FMC. To send the commands, the attacker must have root privileges for at least one affected sensor or the Cisco FMC. The vulnerability exists because the affected software performs insufficient checks for certain CLI commands, if the commands are executed via a Sourcefire tunnel connection. An attacker could exploit this vulnerability by authenticating with root privileges to a Firepower sensor or Cisco FMC, and then sending specific CLI commands to the Cisco FMC or through the Cisco FMC to another Firepower sensor via the Sourcefire tunnel connection. A successful exploit could allow the attacker to modify device configurations or delete files on the device that is running Cisco FMC Software or on any Firepower device that is managed by Cisco FMC. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-fp-cmd-injection • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 0CVE-2018-15383 – Cisco Adaptive Security Appliance Direct Memory Access Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15383
A vulnerability in the cryptographic hardware accelerator driver 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, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition. Una vulnerabilidad en el controlador del acelerador de hardware criptográfico 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, lo que resulta en una denegación de servicio (DoS) temporal. • http://www.securitytracker.com/id/1041787 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-asa-dma-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
