1) Improper Privilege Management (CVE-ID: CVE-2020-3393)

CWE-ID: CWE-269 - Improper Privilege Management

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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.
