CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-3244 – Cisco ASR 5000 Series Aggregation Services Routers Enhanced Charging Service Rule Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-3244
A vulnerability in the Enhanced Charging Service (ECS) functionality of Cisco ASR 5000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to bypass the traffic classification rules on an affected device. The vulnerability is due to insufficient input validation of user traffic going through an affected device. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to bypass the traffic classification rules and potentially avoid being charged for traffic consumption. Una vulnerabilidad en la funcionalidad Enhanced Charging Service (ECS) de Routers de Servicios de Agregación Cisco ASR 5000 Series, podría permitir a un atacante remoto no autenticado omitir las reglas de clasificación de tráfico sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asr5k-ecs-bypass-2LqfPCL • CWE-20: Improper Input Validation •
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: 7.7EPSS: 0%CPEs: 78EXPL: 0CVE-2019-16027 – Cisco IOS XR Software Intermediate System–to–Intermediate System Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-16027
A vulnerability in the implementation of the Intermediate System–to–Intermediate System (IS–IS) routing protocol functionality in Cisco IOS XR Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition in the IS–IS process. The vulnerability is due to improper handling of a Simple Network Management Protocol (SNMP) request for specific Object Identifiers (OIDs) by the IS–IS process. An attacker could exploit this vulnerability by sending a crafted SNMP request to the affected device. A successful exploit could allow the attacker to cause a DoS condition in the IS–IS process. Una vulnerabilidad en la implementación de la funcionalidad del protocolo de enrutamiento Intermediate System–to–Intermediate System (IS–IS) en Cisco IOS XR Software, podría permitir a un atacante remoto autenticado causar una condición de denegación de servicio (DoS) en el proceso IS–IS. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200122-ios-xr-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: 7.2EPSS: 0%CPEs: 211EXPL: 0CVE-2019-1649 – Cisco Secure Boot Hardware Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2019-1649
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. • http://www.securityfocus.com/bid/108350 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot https://www.kb.cert.org/vuls/id/400865 https://www.us-cert.gov/ics/advisories/icsa-20-072-03 • CWE-284: Improper Access Control CWE-667: Improper Locking •
