Common Weakness Enumeration

CWE-417

Grouping Prohibited

Communication Channel Errors

Status: Draft

API response cwe.mitre.org

Weaknesses in this category are related to improper handling of communication channels and access paths. These weaknesses include problems in creating, managing, or removing alternate channels and alternate paths. Some of these can overlap virtual file problems and are commonly used in "bypass" attacks, such as those that exploit authentication errors.

Grouping entries organize the catalogue and should not be used to map the root cause of a vulnerability.

Mapping guidance

This entry is a Grouping. Using groupings for mapping has been discouraged since 2019. They are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.
