CVSS: 6.8EPSS: 0%CPEs: 4EXPL: 0CVE-2019-16026 – Cisco Mobility Management Entity Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-16026
A vulnerability in the implementation of the Stream Control Transmission Protocol (SCTP) on Cisco Mobility Management Entity (MME) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an eNodeB that is connected to an affected device. The vulnerability is due to insufficient input validation of SCTP traffic. An attacker could exploit this vulnerability by leveraging a man-in-the-middle position between the eNodeB and the MME and then sending a crafted SCTP message to the MME. A successful exploit would cause the MME to stop sending SCTP messages to the eNodeB, triggering a DoS condition. Una vulnerabilidad en la implementación del Stream Control Transmission Protocol (SCTP) en Cisco Mobility Management Entity (MME), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un eNodeB que esté conectado en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-mme-dos • CWE-20: Improper Input Validation •

A vulnerability in the IPsec Manager of Cisco StarOS for Cisco Aggregation Services Router (ASR) 5000 Series Routers and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from being established, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of corrupted Internet Key Exchange Version 2 (IKEv2) messages. An attacker could exploit this vulnerability by sending crafted IKEv2 messages toward an affected router. A successful exploit could allow the attacker to cause the ipsecmgr service to reload. A reload of this service could cause all IPsec VPN tunnels to be terminated and prevent new tunnels from being established until the service has restarted, resulting in a DoS condition. • http://www.securityfocus.com/bid/103935 http://www.securitytracker.com/id/1040721 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-starosasr • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2018-0239
A vulnerability in the egress packet processing functionality of the Cisco StarOS operating system for Cisco Aggregation Services Router (ASR) 5700 Series devices and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to cause an interface on the device to cease forwarding packets. The device may need to be manually reloaded to clear this Interface Forwarding Denial of Service condition. The vulnerability is due to the failure to properly check that the length of a packet to transmit does not exceed the maximum supported length of the network interface card (NIC). An attacker could exploit this vulnerability by sending a crafted IP packet or a series of crafted IP fragments through an interface on the targeted device. A successful exploit could allow the attacker to cause the network interface to cease forwarding packets. • http://www.securityfocus.com/bid/103923 http://www.securitytracker.com/id/1040720 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-staros • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •
