**Name of the Vulnerable Software and Affected Versions** NEC Platforms DT900 and DT900S Series versions 5.0.0.0 through 5.3.4.4 NEC Platforms DT900 and DT900S Series versions 5.4.0.0 through 5.6.0.20 **Description** The issue allows an attacker to access non-documented system settings and change them via the local network without authentication. **Recommendations** For versions 5.0.0.0 through 5.3.4.4, update to a version outside of this range to mitigate the risk. For versions 5.4.0.0 through 5.6.0.20, update to a version outside of this range to mitigate the risk. As a temporary workaround, consider restricting access to the system settings until a patch is available.
