CWE-48 路径等价：'filename'(内部空格)
Path Equivalence: 'file name' (Internal Whitespace)
结构: Simple
Abstraction: Variant
状态: Incomplete
被利用可能性: unkown
基本描述
A software system that accepts path input in the form of internal space ('file(SPACE)name') without appropriate validation can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.

| CVE-2000-0293 | Filenames with spaces allow arbitrary file deletion when the product does not properly quote them; some overlap with path traversal. | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2000-0293 |
| 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. | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2001-1567 |
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).
