A vulnerability exists by allowing low-privileged users to read and update the data in various directories used by the Zenon system. An attacker could exploit the vulnerability by using specially crafted
programs to exploit the vulnerabilities by allowing them to run on the zenon installed hosts.
This issue affects ABB Ability™ zenon: from 11 build through 11 build 106404.
Weakness
One or more system settings or configuration elements can be externally controlled by a user.

Potential Mitigations
- Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
