Reference Description
CVE-2000-0293 Filenames with spaces allow arbitrary file deletion when the product does not
properly quote them; some overlap with path traversal.

Notes
Relationship
This weakness is likely to overlap quoting problems, e.g. the "Program Files" unquoted search
path (CWE-428). It also could be an equivalence issue if filtering removes all extraneous spaces.
Relationship
Whitespace can be a factor in other weaknesses not directly related to equivalence. It can also
be used to spoof icons or hide files with dangerous names (see icon manipulation and visual
truncation in CWE-451).

CWE-49: Path Equivalence: 'filename/' (Trailing Slash)
Weakness ID : 49
Structure : Simple
Abstraction : Variant
Description
The product accepts path input in the form of trailing slash ('filedir/') without appropriate validation,
which can lead to ambiguous path resolution and allow an attacker to traverse the file system to
unintended locations or access arbitrary files.
