CVE-2024-51503

8.0 HIGH

📋 TL;DR

This CVE describes a command injection vulnerability in Trend Micro Deep Security 20 Agent's manual scan feature. Attackers with local access or domain user privileges can execute arbitrary code, potentially leading to privilege escalation and remote code execution on other domain machines. Organizations using Trend Micro Deep Security 20 Agent are affected.

💻 Affected Systems

Products:
  • Trend Micro Deep Security Agent
Versions: 20.0
Operating Systems: Windows, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Requires manual scan feature enabled; attackers need local access or domain user privileges for exploitation.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Domain-wide compromise where an attacker with domain user privileges executes arbitrary code on multiple machines, leading to data exfiltration, ransomware deployment, or complete network takeover.

🟠

Likely Case

Privilege escalation on individual machines where attackers with initial access gain higher privileges, enabling persistence, lateral movement, and credential harvesting.

🟢

If Mitigated

Limited to isolated incidents on individual machines with proper segmentation and monitoring, preventing lateral movement and containing the impact.

🌐 Internet-Facing: LOW
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires initial access; domain user privileges enable remote attacks within the same domain.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 20.0.1-2902 or later

Vendor Advisory: https://success.trendmicro.com/en-US/solution/KA-0018154

Restart Required: Yes

Instructions:

1. Download the latest Deep Security Agent update from Trend Micro. 2. Deploy the update to all affected systems. 3. Restart the Deep Security Agent service.

🔧 Temporary Workarounds

Disable Manual Scan Feature

all

Temporarily disable the manual scan functionality to prevent exploitation until patching.

dsa_control -r
Edit configuration to disable manual scans

🧯 If You Can't Patch

  • Implement strict network segmentation to limit lateral movement within the domain.
  • Enforce least privilege access controls and monitor for unusual command execution patterns.

🔍 How to Verify

Check if Vulnerable:

Check Deep Security Agent version; if version is 20.0 and below 20.0.1-2902, it is vulnerable.

Check Version:

dsa_control -v (Linux) or check agent version in Deep Security Manager (Windows)

Verify Fix Applied:

Verify the agent version is 20.0.1-2902 or later and that manual scans function without errors.

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in Deep Security Agent logs
  • Failed or unexpected manual scan attempts

Network Indicators:

  • Suspicious outbound connections from Deep Security Agent processes
  • Unusual domain authentication patterns

SIEM Query:

source="Deep Security" AND (event="command_injection" OR scan="manual")
