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.
Extended Description
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 equivalencemanipulations.

Multi-Factor Vulnerability. Product generates
temporary filenames using long filenames, which become predictable in 8.3
format.
Potential Mitigations
Disable Windows from supporting 8.3 filenames by editing the Windows
registry. Preventing 8.3 filenames will not remove previously generated
8.3 filenames.
