MemberOfViewView - 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).734Weaknesses Addressed by the CERT C Secure Coding Standard (2008)
HasMemberBaseBase - 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.78Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
HasMemberBaseBase - 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.88Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')
HasMemberClassClass - 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.119Improper Restriction of Operations within the Bounds of a Memory Buffer
HasMemberBaseBase - 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.120Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
HasMemberBaseBase - 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.135Incorrect Calculation of Multi-Byte String Length
HasMemberBaseBase - 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.170Improper Null Termination
HasMemberBaseBase - 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.193Off-by-one Error
HasMemberBaseBase - 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.464Addition of Data Structure Sentinel
HasMemberVariantVariant - a weakness that is linked to a certain type of product, typically involving a specific language or technology. More specific than a Base weakness. Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource.686Function Call With Incorrect Argument Type
HasMemberClassClass - 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.704Incorrect Type Conversion or Cast
+ 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.

Relationship

In the 2008 version of the CERT C Secure Coding standard, the following rules were mapped to the following CWE IDs:

  • CWE-78 STR02-C Sanitize data passed to complex subsystems
  • CWE-88 STR02-C Sanitize data passed to complex subsystems
  • CWE-119 STR31-C Guarantee that storage for strings has sufficient space for character data and the null terminator
  • CWE-119 STR32-C Null-terminate byte strings as required
  • CWE-119 STR33-C Size wide character strings correctly
  • CWE-120 STR35-C Do not copy data from an unbounded source to a fixed-length array
  • CWE-135 STR33-C Size wide character strings correctly
  • CWE-170 STR03-C Do not inadvertently truncate a null-terminated byte string
  • CWE-170 STR32-C Null-terminate byte strings as required
  • CWE-193 STR31-C Guarantee that storage for strings has sufficient space for character data and the null terminator
  • CWE-464 STR03-C Do not inadvertently truncate a null-terminated byte string
  • CWE-464 STR06-C Do not assume that strtok() leaves the parse string unchanged
  • CWE-686 STR37-C Arguments to character handling functions must be representable as an unsigned char
  • CWE-704 STR34-C Cast characters to unsigned types before converting to larger integer sizes
  • CWE-704 STR37-C Arguments to character handling functions must be representable as an unsigned char
