CWE-58 路径等价:Windows8.3形式文件名

Path Equivalence: Windows 8.3 Filename

结构: Simple

Abstraction: Variant

状态: Incomplete

被利用可能性: unkown

基本描述

The software contains a protection mechanism that restricts access to a long filename on a Windows operating system, but the software does not properly restrict access to the equivalent short "8.3" filename.

扩展描述

On later Windows operating systems, a file can have a "long name" and a short name that is compatible with older Windows file systems, with up to 8 characters in the filename and 3 characters for the extension. These "8.3" filenames, therefore, act as an alternate name for files with long names, so they are useful pathname equivalence manipulations.

可能的缓解方案

System Configuration

策略:

Disable Windows from supporting 8.3 filenames by editing the Windows registry. Preventing 8.3 filenames will not remove previously generated 8.3 filenames.
