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 •
CVSS: 8.6EPSS: 0%CPEs: 10EXPL: 0CVE-2019-1869 – Cisco StarOS Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1869
A vulnerability in the internal packet-processing functionality of the Cisco StarOS operating system running on virtual platforms could allow an unauthenticated, remote attacker to cause an affected device to stop processing traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to a logic error that may occur under specific traffic conditions. An attacker could exploit this vulnerability by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to prevent the targeted service interface from receiving any traffic, which would lead to a DoS condition on the affected interface. The device may have to be manually reloaded to recover from exploitation of this vulnerability. • http://www.securityfocus.com/bid/108853 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190619-staros-asr-dos • CWE-824: Access of Uninitialized Pointer •
CVSS: 8.6EPSS: 0%CPEs: 6EXPL: 0CVE-2018-0369
https://notcve.org/view.php?id=CVE-2018-0369
A vulnerability in the reassembly logic for fragmented IPv4 packets of Cisco StarOS running on virtual platforms could allow an unauthenticated, remote attacker to trigger a reload of the npusim process, resulting in a denial of service (DoS) condition. There are four instances of the npusim process running per Service Function (SF) instance, each handling a subset of all traffic flowing across the device. It is possible to trigger a reload of all four instances of the npusim process around the same time. The vulnerability is due to improper handling of fragmented IPv4 packets containing options. An attacker could exploit this vulnerability by sending a malicious IPv4 packet across an affected device. • http://www.securityfocus.com/bid/104723 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180711-staros-dos • CWE-20: Improper Input Validation •
