Trend Micro Apex One: Improper Access Control
CVE-2024-37289 is a high-severity improper access control vulnerability in Trend Micro Apex One from Trend Micro, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 14.0.0.12980 as the first without the flaw, so updating Trend Micro Apex One to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.63% chance of exploitation within 30 days, higher than 51% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Trend Micro Apex One to 14.0.0.12980 or a later version.
- Update Trend Micro Apex One as a Service to 14.0.13139 or a later version.
- Update apex_one to 14.0.0.12980 or 14.0.13139, whichever matches your release line, or a later version.

Official description
An improper access control vulnerability in Trend Micro Apex One 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.

The underlying weakness: Improper Access Control
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
