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: 6.1EPSS: 0%CPEs: 1EXPL: 0CVE-2018-0480 – Cisco IOS XE Software Errdisable Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0480
A vulnerability in the errdisable per VLAN feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause the device to crash, leading to a denial of service (DoS) condition. The vulnerability is due to a race condition that occurs when the VLAN and port enter an errdisabled state, resulting in an incorrect state in the software. An attacker could exploit this vulnerability by sending frames that trigger the errdisable condition. A successful exploit could allow the attacker to cause the affected device to crash, leading to a DoS condition. Una vulnerabilidad en la característica errdisable per VLAN en Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar haga que el dispositivo se cierre inesperadamente, provocando una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105400 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-errdisable • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0467 – Cisco IOS and IOS XE Software IPv6 Hop-by-Hop Options Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0467
A vulnerability in the IPv6 processing code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect handling of specific IPv6 hop-by-hop options. An attacker could exploit this vulnerability by sending a malicious IPv6 packet to or through the affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. Una vulnerabilidad en el código de procesamiento IPv6 en Cisco IOS y Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar haga que el dispositivo se reinicie. • 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-ipv6hbh • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0472 – Cisco IOS XE Software and Cisco ASA 5500-X Series Adaptive Security Appliance IPsec Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0472
A vulnerability in the IPsec driver code of multiple Cisco IOS XE Software platforms and the Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to improper processing of malformed IPsec Authentication Header (AH) or Encapsulating Security Payload (ESP) packets. An attacker could exploit this vulnerability by sending malformed IPsec packets to be processed by an affected device. An exploit could allow the attacker to cause a reload of the affected device. Una vulnerabilidad en el código del controlador IPsec de múltiples plataformas Cisco IOS XE Software y Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) podría permitir que un atacante remoto no autenticado provoque la recarga del dispositivo. • http://www.securityfocus.com/bid/105418 http://www.securitytracker.com/id/1041735 http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-04 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ipsec • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0470 – Cisco IOS XE Software HTTP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0470
A vulnerability in the web framework of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a buffer overflow condition on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the affected software improperly parsing malformed HTTP packets that are destined to a device. An attacker could exploit this vulnerability by sending a malformed HTTP packet to an affected device for processing. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, resulting in a DoS condition. Una vulnerabilidad en el framework web de Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar provoque un desbordamiento de búfer en un dispositivo afectado, lo que resulta en una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105397 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-webdos • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •
