A link following vulnerability in the scanning function of Trend Micro Apex One and Worry-Free Business Security agents could allow a local attacker to escalate privileges on affected installations. The resolution for this issue has been deployed automatically via ActiveUpdate to customers in an updated Spyware pattern. Customers who are up-to-date on detection patterns are not required to take any additional steps to mitigate this issue.

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.

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.
