A link following vulnerability in the Trend Micro Deep Security 20.0 and Trend Micro Cloud One - Endpoint and Workload Security Agent could allow a local attacker to escalate privileges on affected installations.

Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this 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.

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.
