A privilege escalation vulnerability in Trend Micro Antivirus for Mac 2019 (v9.0.1379 and below) could potentially allow an attacker to create a symbolic link to a target file and modify it.

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
Antivirus Trendmicro * 9.0.1379 (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.
