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: 4.4EPSS: 0%CPEs: 59EXPL: 0CVE-2019-1762 – Cisco IOS and IOS XE Software Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-1762
A vulnerability in the Secure Storage feature of Cisco IOS and IOS XE Software could allow an authenticated, local attacker to access sensitive system information on an affected device. The vulnerability is due to improper memory operations performed at encryption time, when affected software handles configuration updates. An attacker could exploit this vulnerability by retrieving the contents of specific memory locations of an affected device. A successful exploit could result in the disclosure of keying materials that are part of the device configuration, which can be used to recover critical system information. Una vulnerabilidad en la funcionalidad de almacenamiento seguro de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante local no autenticado acceda a información sensible del sistema en un dispositivo afectado. • http://www.securityfocus.com/bid/107594 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-info • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.3EPSS: 0%CPEs: 45EXPL: 1CVE-2019-1759 – Cisco IOS XE Software Gigabit Ethernet Management Interface Access Control List Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1759
A vulnerability in access control list (ACL) functionality of the Gigabit Ethernet Management interface of Cisco IOS XE Software could allow an unauthenticated, remote attacker to reach the configured IP addresses on the Gigabit Ethernet Management interface. The vulnerability is due to a logic error that was introduced in the Cisco IOS XE Software 16.1.1 Release, which prevents the ACL from working when applied against the management interface. An attacker could exploit this issue by attempting to access the device via the management interface. Una vulnerabilidad en la funcionalidad de listas de control de acceso (ACL) de la interfaz Gigabit Ethernet Management del software Cisco IOS XE podría permitir que un atacante remoto no autenticado alcance las direcciones IP configuradas de la interfaz Gigabit Ethernet Management. La vulnerabilidad se debe a un error de lógica que se introdujo en la versión 16.1.1 del software Cisco IOS XE, que evita que la ACL trabaje cuando se aplica contra la interfaz de gestión. • https://github.com/r3m0t3nu11/CVE-2019-1759-csrf-js-rce http://www.securityfocus.com/bid/107660 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-mgmtacl • CWE-284: Improper Access Control CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2019-1760
A vulnerability in Performance Routing Version 3 (PfRv3) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the affected device to reload. The vulnerability is due to the processing of malformed smart probe packets. An attacker could exploit this vulnerability by sending specially crafted smart probe packets at the affected device. A successful exploit could allow the attacker to reload the device, resulting in a denial of service (DoS) attack on an affected system. Una vulnerabilidad en Performance Routing Version 3 (PfRv3) del software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque que el dispositivo afectado se recargue. • http://www.securityfocus.com/bid/107611 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-pfrv3 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2019-1761
A vulnerability in the Hot Standby Router Protocol (HSRP) subsystem of Cisco IOS and IOS XE Software could allow an unauthenticated, adjacent attacker to receive potentially sensitive information from an affected device. The vulnerability is due to insufficient memory initialization. An attacker could exploit this vulnerability by receiving HSRPv2 traffic from an adjacent HSRP member. A successful exploit could allow the attacker to receive potentially sensitive information from the adjacent device. Una vulnerabilidad en el subsistema Hot Standby Router Protocol (HSRP) de los softwares Cisco IOS y IOS XE podría permitir que un atacante adyacente sin autenticar reciba información potencialmente sensible desde un dispositivo afectado. • http://www.securityfocus.com/bid/107620 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-ios-infoleak • CWE-665: Improper Initialization •
