CWE Grouping: Permissions, Privileges, and Access Controls

Grouping ID: 264
Vulnerability Mapping: PROHIBITED This CWE ID must not be used to map to real-world vulnerabilities
+ Summary
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
+ Membership
Nature Type ID Name
MemberOf ViewView - a subset of CWE entries that provides a way of examining CWE content. The two main view structures are Slices (flat lists) and Graphs (containing relationships between entries). 635 Weaknesses Originally Used by NVD from 2008 to 2016
MemberOf GroupingGrouping - a CWE entry that contains a set of other entries that share a common characteristic. 1345 OWASP Top Ten 2021 Category A01:2021 - Broken Access Control
+ Vulnerability Mapping Notes
Usage PROHIBITED
(this CWE ID must not be used to map to real-world vulnerabilities)
Reason Grouping

Rationale

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 [REF-1287]. This CWE ID may have become widely-used because of NIST's usage in NVD from 2008 to 2016 (see CWE-635 view, updated to the CWE-1003 view in 2016).

Comments

Some weakness-oriented alternatives might be found as descendants under Improper Access Control (CWE-284). Note: use of CWE-284 is Discouraged; see CWE-284's Mapping Notes.
