CVSS: 7.4EPSS: 0%CPEs: 567EXPL: 0CVE-2019-1746 – Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1746
A vulnerability in the Cluster Management Protocol (CMP) processing code in 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 insufficient input validation when processing CMP management packets. An attacker could exploit this vulnerability by sending malicious CMP management packets to an affected device. A successful exploit could cause the switch to crash, resulting in a DoS condition. The switch will reload automatically. • http://www.securityfocus.com/bid/107612 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-cmp-dos • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 164EXPL: 0CVE-2019-1739 – Cisco IOS and IOS XE Software Network-Based Application Recognition Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1739
A vulnerability in the Network-Based Application Recognition (NBAR) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability is due to a parsing issue on DNS packets. An attacker could exploit this vulnerability by sending crafted DNS packets through routers that are running an affected version and have NBAR enabled. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la funcionalidad NBAR (Network-Based Application Recognition) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque que el dispositivo afectado se recargue. • http://www.securityfocus.com/bid/107597 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-nbar • CWE-20: Improper Input Validation •

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 •
