Description

The vulnerability allows a local user to gain elevated privileges on the system.

The vulnerability exists in the application-hosting subsystem due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem . A local user can execute arbitrary CLI commands with root privileges.

Install updates from vendor's website.
