Common Weakness Enumeration
The Common Weakness Enumeration (CWE) is a category system for software weaknesses and vulnerabilities. It is sustained by a community project with the goals of understanding flaws in software and creating automated tools that can be used to identify, fix, and prevent those flaws. The project is sponsored by the National Cybersecurity FFRDC, which is owned by The MITRE Corporation, with support from US-CERT and the National Cyber Security Division of the U.S. Department of Homeland Security.
Version 3.2 of the CWE standard was released in January 2019.
- CWE category 121 is for stack-based buffer overflows.
Common Weakness Enumeration (CWE) Compatibility program allows a service or a product to be reviewed and registered as officially "CWE-Compatible" and "CWE-Effective". The program assists organizations in selecting the right software tools and learning about possible weaknesses and their possible impact.
In order to obtain CWE Compatible status a product or a service must meet 4 out of 6 requirements, shown below:
|CWE Searchable||users may search security elements using CWE identifiers|
|CWE Output||security elements presented to users includes, or allows users to obtain, associated CWE identifiers|
|Mapping Accuracy||security elements accurately link to the appropriate CWE identifiers|
|CWE Documentation||capability's documentation describes CWE, CWE compatibility, and how CWE-related functionality in the capability is used|
|CWE Coverage||for CWE-Compatibility and CWE-Effectiveness, the capability's documentation explicitly lists the CWE-IDs that the capability claims coverage and effectiveness against locating in software|
|CWE Test Results||for CWE-Effectiveness, test results from the capability showing the results of assessing software for the CWEs are posted on the CWE Web site|
There are 48 organizations as of January 2018 that develop and maintain products and services that achieved CWE Compatible status.

Some researchers think that ambiguities in CWE can be avoided or reduced.
