CVE-2019-12658 – Cisco IOS XE Software Filesystem Exhaustion Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12658
A vulnerability in the filesystem resource management code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to exhaust filesystem resources on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to ineffective management of the underlying filesystem resources. An attacker could exploit this vulnerability by performing specific actions that result in messages being sent to specific operating system log files. A successful exploit could allow the attacker to exhaust available filesystem space on an affected device. This could cause the device to crash and reload, resulting in a DoS condition for clients whose network traffic is transiting the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-fsdos • CWE-400: Uncontrolled Resource Consumption •
CVE-2019-12657 – Cisco IOS XE Software Unified Threat Defense Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12657
A vulnerability in Unified Threat Defense (UTD) in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper validation of IPv6 packets through the UTD feature. An attacker could exploit this vulnerability by sending IPv6 traffic through an affected device that is configured with UTD. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en Unified Threat Defense (UTD) en el Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado causar que un dispositivo afectado se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-utd • CWE-20: Improper Input Validation •
CVE-2018-0179 – Cisco IOS Software Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0179
Multiple vulnerabilities in the Login Enhancements (Login Block) feature of Cisco IOS Software could allow an unauthenticated, remote attacker to trigger a reload of an affected system, resulting in a denial of service (DoS) condition. These vulnerabilities affect Cisco devices that are running Cisco IOS Software Release 15.4(2)T, 15.4(3)M, or 15.4(2)CG and later. Cisco Bug IDs: CSCuy32360, CSCuz60599. Múltiples vulnerabilidades en la característica Login Enhancements (Login Block) de Cisco IOS Software permite que un atacante remoto no autenticado desencadene el reinicio de un sistema afectado. Esto resulta una condición de denegación de servicio (DoS). • http://www.securityfocus.com/bid/103556 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-slogin • CWE-399: Resource Management Errors •

CVE-2018-0177
https://notcve.org/view.php?id=CVE-2018-0177
A vulnerability in the IP Version 4 (IPv4) processing code of Cisco IOS XE Software running on Cisco Catalyst 3850 and Cisco Catalyst 3650 Series Switches could allow an unauthenticated, remote attacker to cause high CPU utilization, traceback messages, or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain IPv4 packets. An attacker could exploit this vulnerability by sending specific IPv4 packets to an IPv4 address on an affected device. A successful exploit could allow the attacker to cause high CPU utilization, traceback messages, or a reload of the affected device that leads to a DoS condition. If the switch does not reboot when under attack, it would require manual intervention to reload the device. • http://www.securityfocus.com/bid/103563 http://www.securitytracker.com/id/1040588 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-ipv4 • CWE-19: Data Processing Errors •
