Summary

Categories in the Common Weakness Enumeration (CWE) group entries based on some common characteristic or attribute.

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.
