Analysis Summary
CVE-2023-20016 CVSS:6.3
Cisco FXOS Software and UCS Manager Software could allow a local attacker to obtain sensitive information, caused by a flaw in the encryption method used for the backup function. By sending a specially-crafted HTTP request, an attacker could exploit this vulnerability to obtain sensitive information stored in full state and configuration backup files, and use this information to launch further attacks against the affected system.
CVE-2023-20050 CVSS:4.4
Cisco NX-OS Software could allow a local authenticated attacker to execute arbitrary commands on the system, caused by improper validation of arguments that are passed to specific CLI commands. By sending a specially-crafted input as the argument, an attacker could exploit this vulnerability to execute arbitrary commands on the underlying operating system with the privileges of the currently logged-in user.
CVE-2023-20015 CVSS:6
Cisco Firepower 4100, 9300 Security Appliances, and UCS Fabric Interconnects could allow a local authenticated attacker to execute arbitrary commands on the system, caused by improper input validation of commands supplied by the user.
