Weaknesses in this category are related to the "Poorly Documented or Undocumented Features" category from the SEI ETF "Categories of Security Vulnerabilities in ICS" as published in March 2022: "Undocumented capabilities and configurations pose a risk by not having a clear understanding of what the device is specifically supposed to do and only do. Therefore possibly opening up the attack surface and vulnerabilities." Note: members of this category include "Nearest IT Neighbor" recommendations from the report, as well as suggestions by the CWE team. These relationships are likely to change in future CWE versions.
