CVSS: 8.6EPSS: 1%CPEs: 9EXPL: 0CVE-2018-15454 – Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software Denial of Service Vulnerability
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.

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 •
CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 0CVE-2018-15399 – Cisco Adaptive Security Appliance TCP Syslog Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15399
A vulnerability in the TCP syslog module of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust the 1550-byte buffers on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing boundary check in an internal function. An attacker could exploit this vulnerability by establishing a man-in-the-middle position between an affected device and its configured TCP syslog server and then maliciously modifying the TCP header in segments that are sent from the syslog server to the affected device. A successful exploit could allow the attacker to exhaust buffer on the affected device and cause all TCP-based features to stop functioning, resulting in a DoS condition. The affected TCP-based features include AnyConnect SSL VPN, clientless SSL VPN, and management connections such as Secure Shell (SSH), Telnet, and HTTPS. • http://www.securitytracker.com/id/1041785 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-asa-syslog-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 97%CPEs: 14EXPL: 7CVE-2018-0296 – Cisco Adaptive Security Appliance (ASA) Denial-of-Service Vulnerability
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 •
