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: 4.3EPSS: 0%CPEs: 1762EXPL: 0CVE-2019-1761 – Cisco IOS and IOS XE Software Hot Standby Router Protocol Information Leak Vulnerability
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 •

https://notcve.org/view.php?id=CVE-2019-1757
A vulnerability in the Cisco Smart Call Home feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software. Una vulnerabilidad en la funcionalidad Cisco Smart Call Home de los softwares Cisco IOS y Cisco IOS XE podría permitir que un atacante remoto no autenticado obtenga acceso de lectura no autorizado a datos sensibles mediante un certificado inválido. • http://www.securityfocus.com/bid/107617 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-call-home-cert • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2019-1758
A vulnerability in 802.1x function of Cisco IOS Software on the Catalyst 6500 Series Switches could allow an unauthenticated, adjacent attacker to access the network prior to authentication. The vulnerability is due to how the 802.1x packets are handled in the process path. An attacker could exploit this vulnerability by attempting to connect to the network on an 802.1x configured port. A successful exploit could allow the attacker to intermittently obtain access to the network. Una vulnerabilidad en la función 802.1x del software Cisco IOS en los switches Catalyst 6500 Series podría permitir que un atacante adyacente sin autenticar acceda a la red antes de autenticarse. • http://www.securityfocus.com/bid/107616 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-c6500 • CWE-287: Improper Authentication •
