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: 8.8EPSS: 0%CPEs: 155EXPL: 0CVE-2019-1745 – Cisco IOS XE Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1745
A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with elevated privileges. The vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected commands. An exploit could allow the attacker to gain root privileges on the affected device. Una vulnerabilidad en el software Cisco IOS XE podría permitir que un atacante local autenticado inyecte comandos arbitrarios que se ejecutan con privilegios elevados. • http://www.securityfocus.com/bid/107588 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-xecmd • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 8.6EPSS: 0%CPEs: 149EXPL: 0CVE-2019-1740 – Cisco IOS and IOS XE Software Network-Based Application Recognition Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1740
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 are 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: 8.1EPSS: 0%CPEs: 2EXPL: 0CVE-2018-15372 – Cisco IOS XE Software MACsec MKA Using EAP-TLS Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2018-15372
A vulnerability in the MACsec Key Agreement (MKA) using Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to bypass authentication and pass traffic through a Layer 3 interface of an affected device. The vulnerability is due to a logic error in the affected software. An attacker could exploit this vulnerability by connecting to and passing traffic through a Layer 3 interface of an affected device, if the interface is configured for MACsec MKA using EAP-TLS and is running in access-session closed mode. A successful exploit could allow the attacker to bypass 802.1x network access controls and gain access to the network. Una vulnerabilidad en la funcionalidad MACsec Key Agreement (MKA) empleando Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) de Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar omita la autenticación y pase tráfico a través de una interfaz Layer 3 de un dispositivo afectado. • http://www.securityfocus.com/bid/105416 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-macsec • CWE-284: Improper Access Control •
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 •
