CVE-2023-25146

A security agent link following vulnerability in the Trend Micro Apex One agent could allow a local attacker to quarantine a file, delete the original folder and replace with a junction to an arbitrary location, ultimately leading to an arbitrary file dropped to an arbitrary location.

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.

Affected Software

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.
