CVE-2024-58105
📋 TL;DR
This vulnerability in Trend Micro Apex One Security Agent Plug-in User Interface Manager allows a local attacker with low-privileged access to bypass security controls and execute arbitrary code on affected systems. It affects Trend Micro Apex One installations where the attacker already has some foothold on the target machine. This is an additional bypass not covered by the related CVE-2024-58104.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining SYSTEM/administrator privileges, installing persistent malware, stealing credentials, and moving laterally across the network.
Likely Case
Local privilege escalation allowing attacker to disable security controls, install additional payloads, and maintain persistence on the compromised host.
If Mitigated
Limited impact due to proper network segmentation, endpoint protection, and least privilege principles preventing lateral movement.
🎯 Exploit Status
Requires local access and ability to execute low-privileged code first. This is a bypass vulnerability building on CVE-2024-58104.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to vendor advisory KA-0018217 for specific patched versions
Vendor Advisory: https://success.trendmicro.com/en-US/solution/KA-0018217
Restart Required: No
Instructions:
1. Review Trend Micro advisory KA-0018217. 2. Apply the latest security patch/update for Trend Micro Apex One. 3. Verify the patch is applied successfully. 4. Consider updating all affected endpoints.
🔧 Temporary Workarounds
Restrict local user privileges
allImplement least privilege principles to limit what low-privileged users can execute on endpoints
Network segmentation
allSegment networks to limit lateral movement if endpoint is compromised
🧯 If You Can't Patch
- Implement strict application whitelisting to prevent unauthorized code execution
- Deploy additional endpoint detection and response (EDR) solutions to monitor for privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check Trend Micro Apex One agent version and compare against patched versions in advisory KA-0018217Check Version:
Check Trend Micro Apex One console or agent interface for version informationVerify Fix Applied:
Verify Trend Micro Apex One agent has been updated to patched version specified in vendor advisory📡 Detection & Monitoring
