Is this vulnerability remotely exploitable from the internet?

Yes, if the MajorDoMo interface is reachable over the network (for example, exposed to the internet or a wider internal network), an unauthenticated attacker can exploit the issue by sending crafted requests to the market module endpoint.

Does an attacker need a valid user account to exploit this?

No. The vulnerability exists because administrative actions are tied to a request parameter rather than to the caller's authenticated privileges. As a result, no login or valid session is required to trigger module uninstallation.

What is the safest general fix pattern for this issue?

The safest pattern is to enforce strict authentication and authorization checks at the start of any admin or module-management code, and to treat all mode/action parameters as untrusted. Sensitive operations like install, uninstall, and update should only execute after verifying that the caller holds an appropriate admin role and is operating from a legitimate session.
