CWE-58: Path Equivalence: Windows 8.3 Filename

Variant Incomplete Simple

CWE版本: 4.18

更新日期: 2025-09-09

弱点描述

The product contains a protection mechanism that restricts access to a long filename on a Windows operating system, but it 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.

常见后果

影响范围: Confidentiality Integrity

技术影响: Read Files or Directories Modify Files or Directories

潜在缓解措施

阶段: System Configuration

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