CVE-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 •
CVE-2019-1615 – Cisco NX-OS Software Image Signature Verification Vulnerability
https://notcve.org/view.php?id=CVE-2019-1615
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 is due to improper verification of digital signatures for software images. An attacker could exploit this vulnerability by loading an unsigned software image on an affected device. A successful exploit could allow the attacker to boot a malicious software image. Note: The fix for this vulnerability requires a BIOS upgrade as part of the software upgrade. • http://www.securityfocus.com/bid/107397 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-sig-verif • CWE-347: Improper Verification of Cryptographic Signature •
CVE-2019-1613 – Cisco NX-OS Software CLI Command Injection Vulnerability (CVE-2019-1613)
https://notcve.org/view.php?id=CVE-2019-1613
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability. • http://www.securityfocus.com/bid/107392 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190306-nxos-cmdinj-1613 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
