    + Objective
    CWE nodes in this view (slice) were used by NIST to categorize vulnerabilities within NVD, from 2008 to 2016. This original version has been used by many other projects.
    + Membership
    Nature Type ID Name
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 16 Configuration
    HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 20 Improper Input Validation
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 59 Improper Link Resolution Before File Access ('Link Following')
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 94 Improper Control of Generation of Code ('Code Injection')
    HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 119 Improper Restriction of Operations within the Bounds of a Memory Buffer
    HasMember BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. 134 Use of Externally-Controlled Format String
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 189 Numeric Errors
    HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 200 Exposure of Sensitive Information to an Unauthorized Actor
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 255 Credentials Management Errors
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 264 Permissions, Privileges, and Access Controls
    HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 287 Improper Authentication
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 310 Cryptographic Issues
    HasMember CompositeComposite - a Compound Element that consists of two or more distinct weaknesses, in which all weaknesses must be present at the same time in order for a potential vulnerability to arise. Removing any of the weaknesses eliminates or sharply reduces the risk. One weakness, X, can be "broken down" into component weaknesses Y and Z. There can be cases in which one weakness might not be essential to a composite, but changes the nature of the composite when it becomes a vulnerability. 352 Cross-Site Request Forgery (CSRF)
    HasMember ClassClass - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. More specific than a Pillar Weakness, but more general than a Base Weakness. Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. 362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
    HasMember CategoryCategory - a CWE entry that contains a set of other entries that share a common characteristic. 399 Resource Management Errors

    Usage: PROHIBITED

    (this CWE ID must not be used to map to real-world vulnerabilities)

    Reason: View

    Rationale:

    This entry is a View. Views are not weaknesses and therefore inappropriate to describe the root causes of vulnerabilities.

    Comments:

    Use this View or other Views to search and navigate for the appropriate weakness.

    Maintenance

    In Summer 2007, NIST began using this set of CWE elements to classify CVE entries within the National Vulnerability Database (NVD). The data was made publicly available beginning in 2008. In 2016, NIST began using a different list as derived from the "Weaknesses for Simplified Mapping of Published Vulnerabilities" view (CWE-1003).
