Microsoft Office Click-To-Run Elevation of Privilege Vulnerability

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
365_apps Microsoft - (including) - (including)
Office Microsoft 2019 (including) 2019 (including)
Office_long_term_servicing_channel Microsoft 2021 (including) 2021 (including)

Potential Mitigations

  • 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.
