CVSS: 7.2EPSS: 0%CPEs: 73EXPL: 0CVE-2019-1812 – Cisco NX-OS CLI Command Software Image Signature Verification Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1812
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 software Cisco NX-OS podría permitir que un atacante local autenticado con credenciales de administrador para instalar una imagen de software malintencionado en un dispositivo afectado. La vulnerabilidad se debe a que las firmas digitales del software 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: 35EXPL: 0CVE-2019-1808 – Cisco MDS 9700 Series Multilayer Directors and Nexus 7000/7700 Series Switches Software Patch Signature Verification Vulnerability
https://notcve.org/view.php?id=CVE-2019-1808
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 patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by loading an unsigned software patch on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. Una vulnerabilidad en la función Image Signature Verification del programa NX-OS de Cisco podría permitir que un atacante local que ha accedido con credenciales de administrador pueda instalar un parche de un programa malicioso en un dispositivo afectado. • http://www.securityfocus.com/bid/108367 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-spsv • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 6.7EPSS: 0%CPEs: 41EXPL: 0CVE-2019-1809 – Cisco NX-OS Software Patch Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1809
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 patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. 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 un parche de programa malicioso en un dispositivo afectado. • http://www.securityfocus.com/bid/108375 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-psvb • 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 •
