CWE-64: Windows Shortcut Following (.LNK)

VariantLikelihood of exploit: Low

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.

Consequences

  • Confidentiality, Integrity: Read Files or Directories, Modify Files or Directories

How to prevent it

  • 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 an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
