Trend Micro Apex One: Incorrect Privilege Assignment

Published Updated By the CyberSecBulletin desk

CVE-2024-52049 is a high-severity incorrect privilege assignment 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 14.0.0.13140 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 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

A LogServer link following vulnerability in Trend Micro Apex One could allow a local attacker to escalate privileges on affected installations. This vulnerability is similar to, but not identical to CVE-2024-52048. 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: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that 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.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
