CVSS: 8.6EPSS: 0%CPEs: 615EXPL: 0CVE-2019-1737 – Cisco IOS and IOS XE Software IP Service Level Agreement Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1737
A vulnerability in the processing of IP Service Level Agreement (SLA) packets by Cisco IOS Software and Cisco IOS XE software could allow an unauthenticated, remote attacker to cause an interface wedge and an eventual denial of service (DoS) condition on the affected device. The vulnerability is due to improper socket resources handling in the IP SLA responder application code. An attacker could exploit this vulnerability by sending crafted IP SLA packets to an affected device. An exploit could allow the attacker to cause an interface to become wedged, resulting in an eventual denial of service (DoS) condition on the affected device. Una vulnerabilidad en el procesamiento de los paquetes IP SLA (Service Level Agreement) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque una cuña (wedge) en la interfaz y, finalmente, una denegación de servicio (DoS) en el dispositivo afectado. • http://www.securityfocus.com/bid/107604 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-ipsla-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.1EPSS: 0%CPEs: 149EXPL: 0CVE-2018-0282 – Cisco IOS and IOS XE Software TCP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0282
A vulnerability in the TCP socket code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a state condition between the socket state and the transmission control block (TCB) state. While this vulnerability potentially affects all TCP applications, the only affected application observed so far is the HTTP server. An attacker could exploit this vulnerability by sending specific HTTP requests at a sustained rate to a reachable IP address of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition on an affected device. • http://www.securityfocus.com/bid/106510 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190109-tcp • CWE-371: State Issues •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2018-15373 – Cisco IOS and IOS XE Software Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15373
A vulnerability in the implementation of Cisco Discovery Protocol functionality in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust memory on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper memory handling by the affected software when the software processes high rates of Cisco Discovery Protocol packets that are sent to a device. An attacker could exploit this vulnerability by sending a high rate of Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to exhaust memory on the affected device, resulting in a DoS condition. Una vulnerabilidad en la implementación de la funcionalidad Cisco Discovery Protocol en Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar agote la memoria de un dispositivo afectado, provocando una denegación de servicio (DoS) en consecuencia. • http://www.securityfocus.com/bid/105413 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cdp-dos • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.2EPSS: 0%CPEs: 2EXPL: 0CVE-2018-15376 – Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers Arbitrary Memory Write Vulnerabilities
https://notcve.org/view.php?id=CVE-2018-15376
A vulnerability in the embedded test subsystem of Cisco IOS Software for Cisco 800 Series Industrial Integrated Services Routers could allow an authenticated, local attacker to write arbitrary values to arbitrary locations in the memory space of an affected device. The vulnerability is due to the presence of certain test commands that were intended to be available only in internal development builds of the affected software. An attacker could exploit this vulnerability by using these commands on an affected device. A successful exploit could allow the attacker to write arbitrary values to arbitrary locations in the memory space of the affected device. Una vulnerabilidad en el subsistema de pruebas embebido de Cisco IOS Software para routers Cisco 800 Series Industrial Integrated Services podría permitir que un atacante local autenticado escriba valores arbitrarios en ubicaciones arbitrarias en el espacio de memoria de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ir800-memwrite • CWE-123: Write-what-where Condition •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0475 – Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0475
A vulnerability in the implementation of the cluster feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation when handling Cluster Management Protocol (CMP) messages. An attacker could exploit this vulnerability by sending a malicious CMP message to an affected device. A successful exploit could allow the attacker to cause the switch to crash and reload or to hang, resulting in a DoS condition. If the switch hangs it will not reboot automatically, and it will need to be power cycled manually to recover. • http://www.securityfocus.com/bid/105404 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cmp • CWE-20: Improper Input Validation •
