CVSS: 7.4EPSS: 0%CPEs: 930EXPL: 0CVE-2019-1748 – Cisco IOS and IOS XE Software Network Plug-and-Play Agent Certificate Validation Vulnerability
https://notcve.org/view.php?id=CVE-2019-1748
A vulnerability in the Cisco Network Plug-and-Play (PnP) agent of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data. The vulnerability exists because the affected software insufficiently validates certificates. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt and modify confidential information on user connections to the affected software. Una vulnerabilidad en el agente Cisco Network Plug-and-Play (PnP) de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado obtenga acceso no autorizado a datos sensibles. • http://www.securityfocus.com/bid/107619 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-pnp-cert • CWE-295: Improper Certificate Validation •
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: 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: 6.5EPSS: 0%CPEs: 1195EXPL: 0CVE-2018-0197 – Cisco IOS and IOS XE Software VLAN Trunking Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0197
A vulnerability in the VLAN Trunking Protocol (VTP) subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to corrupt the internal VTP database on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to a logic error in how the affected software handles a subset of VTP packets. An attacker could exploit this vulnerability by sending VTP packets in a sequence that triggers a timeout in the VTP message processing code of the affected software. A successful exploit could allow the attacker to impact the ability to create, modify, or delete VLANs and cause a DoS condition. There are workarounds that address this vulnerability. • http://www.securityfocus.com/bid/105424 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-vtp • CWE-20: Improper Input Validation •
