CVE-2024-37289

7.8 HIGH

📋 TL;DR

This vulnerability in Trend Micro Apex One allows a local attacker with low-privileged access to escalate privileges on affected systems. Attackers could gain administrative control over the endpoint security software. Organizations using vulnerable versions of Apex One are affected.

💻 Affected Systems

Products:
  • Trend Micro Apex One
Versions: Specific versions not detailed in references, but all affected versions should be patched
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Affects on-premises Apex One installations. Requires local access to the system.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise where an attacker gains full administrative control over the endpoint security software, potentially disabling protection and accessing sensitive data.

🟠

Likely Case

Local privilege escalation allowing attackers to bypass security controls, install malware, or access protected system resources.

🟢

If Mitigated

Limited impact if proper network segmentation, least privilege access, and endpoint detection are implemented.

🌐 Internet-Facing: LOW - Requires local access to the system, not directly exploitable over the internet.
🏢 Internal Only: HIGH - Once an attacker gains initial foothold on a system, they can escalate privileges to compromise the endpoint security.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Requires local access and ability to execute low-privileged code first. The vulnerability is in improper access control mechanisms.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not specified in references, but Trend Micro has released patches

Vendor Advisory: https://success.trendmicro.com/dcx/s/solution/000298063

Restart Required: Yes

Instructions:

1. Access Trend Micro Apex One management console. 2. Check for available updates. 3. Apply the latest security patch. 4. Restart affected systems as required.

🔧 Temporary Workarounds

Restrict local access

windows

Limit local user access to systems running Apex One to reduce attack surface

Implement application control

windows

Use application whitelisting to prevent unauthorized code execution

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate vulnerable systems
  • Enforce least privilege access controls and monitor for privilege escalation attempts

🔍 How to Verify

Check if Vulnerable:

Check Apex One version against Trend Micro's advisory and verify if patch is applied

Check Version:

Check Apex One console or agent version through system information

Verify Fix Applied:

Confirm patch installation through Apex One management console and verify version is updated

📡 Detection & Monitoring

Log Indicators:

  • Unusual privilege escalation attempts
  • Apex One service manipulation logs
  • Failed authentication attempts followed by successful privileged actions

Network Indicators:

  • Unusual outbound connections from Apex One processes
  • Lateral movement attempts from compromised endpoints

SIEM Query:

source="apex_one" AND (event_type="privilege_escalation" OR process_name="*apex*" AND action="modify")
