Weakness Name
Path Traversal: '../filedir'
Description
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "../" sequences that can resolve to a location that is outside of that directory.
This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory. The "../" manipulation is the canonical manipulation for operating systems that use "/" as directory separators, such as UNIX- and Linux-based systems. In some cases, it is useful for bypassing protection schemes in environments for which "/" is supported but not the primary separator, such as Windows, which uses "\" but can also accept "/".
Common Consequences
Scope: Confidentiality, Integrity
Impact: Read Files or Directories, Modify Files or Directories
