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 •

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 •

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: 8.1EPSS: 0%CPEs: 5EXPL: 1CVE-2018-15465 – Cisco Adaptive Security Appliance Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2018-15465
A vulnerability in the authorization subsystem of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, but unprivileged (levels 0 and 1), remote attacker to perform privileged actions by using the web management interface. The vulnerability is due to improper validation of user privileges when using the web management interface. An attacker could exploit this vulnerability by sending specific HTTP requests via HTTPS to an affected device as an unprivileged user. An exploit could allow the attacker to retrieve files (including the running configuration) from the device or to upload and replace software images on the device. Una vulnerabilidad en el subsistema de autorización de Cisco Adaptive Security Appliance (ASA) Software podría permitir que un atacante remoto autenticado, pero sin privilegios (niveles 0 y 1), realice acciones privilegiadas mediante el uso de la interfaz de gestión web. • http://www.securityfocus.com/bid/106256 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181219-asa-privesc https://www.tenable.com/security/research/tra-2018-46 • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •

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 •
