CWE-66: Failure to Handle File Names that Identify Virtual Resources

Individual Definition in a New Window
Failure to Handle File Names that Identify Virtual Resources
Status: Draft
Weakness ID: 66 (Weakness Base)
Description
Summary

The product does not properly handle a file name that identifies a "virtual" resource that is not directly specified within the directory that is associated with the file name, causing the product to perform file-based operations on a resource that is not a file.

Extended Description

Virtual file names are represented like normal file names, but they are effectively aliases for other resources that do not behave like normal files. Depending on their functionality, they could be alternate entities. They are not necessarily listed in directories.
