CVSS: 7.2EPSS: 0%CPEs: 106EXPL: 0CVE-2019-1780 – Cisco FXOS and NX-OS Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2019-1780
A vulnerability in the CLI of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker with administrator credentials to execute arbitrary commands on the underlying operating system of an affected device with elevated privileges. 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/108392 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-fxos-cmdinj-1780 • 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') •
CVSS: 8.6EPSS: 0%CPEs: 205EXPL: 0CVE-2019-1858 – Cisco FXOS and NX-OS Software Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1858
A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the SNMP application to leak system memory, which could cause an affected device to restart unexpectedly. The vulnerability is due to improper error handling when processing inbound SNMP packets. An attacker could exploit this vulnerability by sending multiple crafted SNMP packets to an affected device. A successful exploit could allow the attacker to cause the SNMP application to leak system memory because of an improperly handled error condition during packet processing. Over time, this memory leak could cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. • http://www.securityfocus.com/bid/108358 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-snmp-dos • CWE-20: Improper Input Validation CWE-755: Improper Handling of Exceptional Conditions •

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.

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.
