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 •
CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-2019-1747 – Cisco IOS and IOS XE Software Short Message Service Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1747
A vulnerability in the implementation of the Short Message Service (SMS) handling functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper processing of SMS protocol data units (PDUs) that are encoded with a special character set. An attacker could exploit this vulnerability by sending a malicious SMS message to an affected device. A successful exploit could allow the attacker to cause the wireless WAN (WWAN) cellular interface module on an affected device to crash, resulting in a DoS condition that would require manual intervention to restore normal operating conditions. Una vulnerabilidad en la implementación de la funcionalidad de manejo de SMS (Short Message Service) del software Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado cree una condición de denegación de servicio (DoS) en un dispositivo afectado. • http://www.securityfocus.com/bid/107599 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-sms-dos • CWE-20: Improper Input Validation •
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: 8.6EPSS: 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 •
CVSS: 7.4EPSS: 0%CPEs: 48EXPL: 0CVE-2018-0165
https://notcve.org/view.php?id=CVE-2018-0165
A vulnerability in the Internet Group Management Protocol (IGMP) packet-processing functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust buffers on an affected device, resulting in a denial of service (DoS) condition, aka a Memory Leak. The vulnerability is due to the affected software insufficiently processing IGMP Membership Query packets that are sent to an affected device. An attacker could exploit this vulnerability by sending a large number of IGMP Membership Query packets, which contain certain values, to an affected device. A successful exploit could allow the attacker to exhaust buffers on the affected device, resulting in a DoS condition that requires the device to be reloaded manually. This vulnerability affects: Cisco Catalyst 4500 Switches with Supervisor Engine 8-E, if they are running Cisco IOS XE Software Release 3.x.x.E and IP multicast routing is configured; Cisco devices that are running Cisco IOS XE Software Release 16.x, if IP multicast routing is configured. • http://www.securityfocus.com/bid/103568 http://www.securitytracker.com/id/1040592 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-igmp • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
