CVSS: 7.2EPSS: 0%CPEs: 73EXPL: 0CVE-2019-1811 – Cisco NX-OS CLI Command Software Image Signature Verification Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1811
A vulnerability in the Image Signature Verification feature of Cisco NX-OS Software could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device. Una vulnerabilidad en la función Image Signature Verification del programa Cisco NX-OS podría permitir que un atacante local autenticado con credenciales de administrador para instalar una imagen de programa malintencionado en un dispositivo afectado. La vulnerabilidad se debe a que las firmas digitales del programa no se verifican correctamente durante la ejecución del comando CLI. • http://www.securityfocus.com/bid/108425 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-sisv2 • CWE-347: Improper Verification of Cryptographic Signature •

CVSS: 6.7EPSS: 0%CPEs: 12EXPL: 0CVE-2019-1810 – Cisco Nexus 3000 Series and 9000 Series Switches in NX-OS Mode CLI Command Software Image Signature Verification Vulnerability
https://notcve.org/view.php?id=CVE-2019-1810
A vulnerability in the Image Signature Verification feature used in an NX-OS CLI command in Cisco Nexus 3000 Series and 9000 Series Switches could allow an authenticated, local attacker with administrator-level credentials to install a malicious software image on an affected device. The vulnerability exists because software digital signatures are not properly verified during CLI command execution. An attacker could exploit this vulnerability to install an unsigned software image on an affected device. Note: If the device has not been patched for the vulnerability previously disclosed in the Cisco Security Advisory cisco-sa-20190306-nxos-sig-verif, a successful exploit could allow the attacker to boot a malicious software image. Una vulnerabilidad en la función Image Signature Verification utilizada en un comando CLI de NX-OS en los switches de las series Nexus 3000 y 9000 de Cisco podría permitir a un atacante local autenticado con credenciales de administrador para instalar una imagen de programa malicioso en un dispositivo afectado. • http://www.securityfocus.com/bid/108431 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-sisv • CWE-347: Improper Verification of Cryptographic Signature •
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 •
