Nom: Path Equivalence: 'file name' (Internal Whitespace)

The product accepts path input in the form of internal space ('file(SPACE)name') 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.

Références Description

CVE-2000-0293

Filenames with spaces allow arbitrary file deletion when the product does not properly quote them; some overlap with path traversal.

CVE-2001-1567

"+" characters in query string converted to spaces before sensitive file/extension (internal space), leading to bypass of access restrictions to the file.

Notes de cartographie des vulnérabilités

Justification : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commentaire : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

NotesNotes

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.
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).
