CWE CATEGORY: 7PK - Input Validation and RepresentationCategory ID: 1005 Vulnerability Mapping:
PROHIBITEDThis CWE ID must not be used to map to real-world vulnerabilities
|
Summary This category represents one of the phyla in the Seven Pernicious Kingdoms vulnerability classification. It includes weaknesses that exist when an application does not properly validate or represent input. According to the authors of the Seven Pernicious Kingdoms, "Input validation and representation problems are caused by metacharacters, alternate encodings and numeric representations. Security problems result from trusting input." Membership Nature | Type | ID | Name |

MemberOf | View - 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). | 700 | Seven Pernicious Kingdoms | HasMember | Class - 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 | Class - 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. | 77 | Improper Neutralization of Special Elements used in a Command ('Command Injection') | HasMember | Base - 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 | Base - 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 | Class - 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. | 99 | Improper Control of Resource Identifiers ('Resource Injection') |
Vulnerability Mapping Notes Usage: PROHIBITED (this CWE ID must not be used to map to real-world vulnerabilities) | Reason: Category | Rationale: This entry is a Category. Using categories for mapping has been discouraged since 2019. Categories are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves. | Comments: See member weaknesses of this category. |
