Summary

In Terminalfour 8 through 8.4.1.1, the userLevel parameter in the user management function is not subject to proper server-side authorization checks. A Power User can intercept and modify this parameter to assign the Administrator role to other lower-privileged accounts or invite a new account and escalate its privileges, and can also change the target account's password.

Risk Assessment

A user with elevated but non-administrative privileges can take full control of accounts, including gaining administrator privileges.

Recommendation

Update Terminalfour to a version later than 8.4.1.1 and enforce proper server-side authorization checks for the userLevel parameter.
