CWE CATEGORY: Pathname Traversal and Equivalence Errors
Category ID: 21
Weaknesses in this category can be used to access files outside of a restricted directory (path traversal) or to perform operations on files that would otherwise be restricted (path equivalence). Files, directories, and folders are so central to information technology that many different weaknesses and variants have been discovered. The manipulations generally involve special characters or sequences in pathnames, or the use of alternate references or channels.
