Haas Controller version 100.20.000.1110 has insufficient granularity of access control when using the "Ethernet Q Commands" service. Any user is able to write macros into registers outside of the authorized accessible range. This could allow a user to access privileged resources or resources out of context.
The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.
