Description

This module exploits an unauthenticated remote code execution vulnerability
in the Eclipse Che machine-exec service (CVE-2025-12548). The machine-exec
service, exposed on port 3333 within Red Hat OpenShift DevSpaces developer
workspace containers, accepts WebSocket connections without authentication.

An attacker can connect to the machine-exec service and execute arbitrary
commands via JSON-RPC over WebSocket. This allows lateral movement between
workspaces and potential cluster compromise.

The vulnerability affects Red Hat OpenShift DevSpaces environments where
the machine-exec service is network-accessible.
