CVSS: 8.6EPSS: 0%CPEs: 17EXPL: 0CVE-2018-15388 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software WebVPN Denial of Service Vulnerability
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-2018-0296
A vulnerability in the web interface of the Cisco Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. It is also possible on certain software releases that the ASA will not reload, but an attacker could view sensitive system information without authentication by using directory traversal techniques. The vulnerability is due to lack of proper input validation of the HTTP URL. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. An exploit could allow the attacker to cause a DoS condition or unauthenticated disclosure of information. • https://www.exploit-db.com/exploits/47220 https://www.exploit-db.com/exploits/44956 https://github.com/yassineaboukir/CVE-2018-0296 https://github.com/milo2012/CVE-2018-0296 https://github.com/bhenner1/CVE-2018-0296 https://github.com/qiantu88/CVE-2018-0296 http://packetstormsecurity.com/files/154017/Cisco-Adaptive-Security-Appliance-Path-Traversal.html http://www.securityfocus.com/bid/104612 http://www.securitytracker.com/id/1041076 https://ics-cert.us-cert.gov/advisories/ICSA- • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2018-0228
A vulnerability in the ingress flow creation functionality of Cisco Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause the CPU to increase upwards of 100% utilization, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to incorrect handling of an internal software lock that could prevent other system processes from getting CPU cycles, causing a high CPU condition. An attacker could exploit this vulnerability by sending a steady stream of malicious IP packets that can cause connections to be created on the targeted device. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition during which traffic through the device could be delayed. This vulnerability applies to either IPv4 or IPv6 ingress traffic. • http://www.securityfocus.com/bid/104220 http://www.securitytracker.com/id/1040724 https://ics-cert.us-cert.gov/advisories/ICSA-18-184-01 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-asa2 • CWE-20: Improper Input Validation CWE-667: Improper Locking •

https://notcve.org/view.php?id=CVE-2018-0242
A vulnerability in the WebVPN web-based management interface of Cisco Adaptive Security Appliance could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.
