[HIGH] CWE-64 Windows Shortcut Following (.LNK)
CWE-64: Windows Shortcut Following (.LNK)
The product, when opening a file or directory, does not sufficiently handle when the file is a Windows shortcut (.LNK) whose target is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.

Potential Mitigations:
[Architecture and Design] Follow the principle of least privilege when assigning access rights to entities in a software system. Denying access to a file can prevent a

Background: Soft links are a UNIX term that is synonymous with simple shortcuts on Windows-based platforms.
Modes of Introduction:
Phase: Implementation
Note: REALIZATION: This weakness is caused during implementation of an architectural security tactic.
Common Consequences:
Scope: Confidentiality, Integrity, Access Control. Impact: Read Files or Directories, Modify Files or Directories, Bypass Protection Mechanism. An attacker may be able to traverse the file system to unintended locations and read or overwrite the contents of unexpe
