Analysis Summary
CVE-2022-20762
Cisco Ultra Cloud Core – Subscriber Microservices Infrastructure (SMI) could allow a local authenticated attacker to gain elevated privileges on the system, caused by insufficient access control in the Common Execution Environment (CEE) ConfD CLI. By authenticating as a CEE ConfD CLI user and executing a specific CLI command, an attacker could exploit this vulnerability to access privileged containers with root privileges.
CVE-2022-20756
Cisco Identity Services Engine is vulnerable to a denial of service, caused by improper handling of certain RADIUS requests. By attempting to authenticate to a network or a service where the access server is using Cisco ISE as the RADIUS server, a remote attacker could exploit this vulnerability to stop processing RADIUS packets.
CVE-2022-20665
Cisco StarOS could allow a local authenticated attacker to execute arbitrary commands on the system, caused by insufficient input validation of CLI commands. By sending-specially crafted commands to the CLI, an attacker could exploit this vulnerability to execute arbitrary commands on the system with root privileges.
CVE-2022-20755
Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by insufficient input validation of user-supplied command arguments. By authenticating to the system as an administrative user and then submitting specially crafted input to the affected command, an attacker could exploit this vulnerability to execute arbitrary commands on the underlying operating system as the root user.
CVE-2022-20754
Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow a remote authenticated attacker to overwrite arbitrary files on the system, caused by insufficient input validation of user-supplied command arguments. By authenticating to the system as an administrative user and then submitting specially crafted input to the affected command, an attacker could exploit this vulnerability to overwrite arbitrary files on the underlying operating system as the root user.
