CVSS: 8.6EPSS: 0%CPEs: 322EXPL: 0CVE-2019-1752 – Cisco IOS and IOS XE Software ISDN Interface Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1752
A vulnerability in the ISDN functions of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of specific values in the Q.931 information elements. An attacker could exploit this vulnerability by calling the affected device with specific Q.931 information elements being present. An 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 las funciones ISDN 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/107589 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-isdn • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 48EXPL: 0CVE-2019-1749 – Cisco Aggregation Services Router 900 Route Switch Processor 3 OSPFv2 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1749
A vulnerability in the ingress traffic validation of Cisco IOS XE Software for Cisco Aggregation Services Router (ASR) 900 Route Switch Processor 3 (RSP3) could allow an unauthenticated, adjacent attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the software insufficiently validates ingress traffic on the ASIC used on the RSP3 platform. An attacker could exploit this vulnerability by sending a malformed OSPF version 2 (OSPFv2) message to an affected device. A successful exploit could allow the attacker to cause a reload of the iosd process, triggering a reload of the affected device and resulting in a DoS condition. Una vulnerabilidad en la validación del tráfico entrante del software Cisco IOS XE para Cisco Aggregation Services Router (ASR) 900 Route Switch Processor 3 (RSP3) podría permitir que un atacante adyacente no autenticado desencadene la recarga de un dispositivo afectado, lo que resulta en una condición de denegación de servicio (DoS). • http://www.securityfocus.com/bid/107615 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-rsp3-ospf • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 42EXPL: 0CVE-2019-1750 – Cisco IOS XE Software Catalyst 4500 Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1750
A vulnerability in the Easy Virtual Switching System (VSS) of Cisco IOS XE Software on Catalyst 4500 Series Switches could allow an unauthenticated, adjacent attacker to cause the switches to reload. The vulnerability is due to incomplete error handling when processing Cisco Discovery Protocol (CDP) packets used with the Easy Virtual Switching System. An attacker could exploit this vulnerability by sending a specially crafted CDP packet. An exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el VSS (Easy Virtual Switching System) del software Cisco IOS XE en los switches Catalyst 4500 Series podría permitir que un atacante adyacente no autenticado provoque la recarga de los switches. • http://www.securityfocus.com/bid/107607 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-evss • CWE-20: Improper Input Validation CWE-388: 7PK - Errors •
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') •
