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 •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0473 – Cisco IOS Software Precision Time Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0473
A vulnerability in the Precision Time Protocol (PTP) subsystem of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition of the Precision Time Protocol. The vulnerability is due to insufficient processing of PTP packets. An attacker could exploit this vulnerability by sending a custom PTP packet to, or through, an affected device. A successful exploit could allow the attacker to cause a DoS condition for the PTP subsystem, resulting in time synchronization issues across the network. Una vulnerabilidad en el subsistema Precision Time Protocol (PTP) de Cisco NX-OS Software podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en el protocolo PTP. • http://www.securityfocus.com/bid/105427 http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ptp • CWE-399: Resource Management Errors •
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 •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0485 – Cisco IOS and IOS XE Software SM-1T3/E3 Service Module Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0485
A vulnerability in the SM-1T3/E3 firmware on Cisco Second Generation Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated Services Router (ISR4451-X) could allow an unauthenticated, remote attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of user input. An attacker could exploit this vulnerability by first connecting to the SM-1T3/E3 module console and entering a string sequence. A successful exploit could allow the attacker to cause the ISR G2 Router or the SM-1T3/E3 module on the ISR4451-X to reload, resulting in a DoS condition on an affected device. Una vulnerabilidad en el firmware SM-1T3/E3 en Cisco Second Generation Integrated Services Routers (ISR G2) y Cisco 4451-X Integrated Services Router (ISR4451-X) podría permitir que un atacante remoto no autenticado provoque que el router ISR G2 o el módulo SM-1T3/E3 en ISR4451-X se recargue, resultando en una denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/105433 http://www.securitytracker.com/id/1041736 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-sm1t3e3 • CWE-19: Data Processing Errors CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2018-15369 – Cisco IOS and IOS XE Software TACACS+ Client Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15369
A vulnerability in the TACACS+ client subsystem of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of crafted TACACS+ response packets by the affected software. An attacker could exploit this vulnerability by injecting a crafted TACACS+ packet into an existing TACACS+ session between an affected device and a TACACS+ server or by impersonating a known, valid TACACS+ server and sending a crafted TACACS+ packet to an affected device when establishing a connection to the device. To exploit this vulnerability by using either method, the attacker must know the shared TACACS+ secret and the crafted packet must be sent in response to a TACACS+ request from a TACACS+ client. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. • http://www.securityfocus.com/bid/105426 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-tacplus • CWE-20: Improper Input Validation •
