CVE-2024-5671

9.8 CRITICAL

📋 TL;DR

CVE-2024-5671 is an insecure deserialization vulnerability in Trellix IPS Manager workflows that allows unauthenticated remote attackers to execute arbitrary code. This affects organizations using vulnerable versions of Trellix IPS Manager, potentially giving attackers full control over the management system.

💻 Affected Systems

Products:
  • Trellix IPS Manager
Versions: Specific versions not detailed in provided references; consult Trellix advisory for exact affected versions
Operating Systems: Windows Server (presumed based on typical IPS Manager deployments)
Default Config Vulnerable: ⚠️ Yes
Notes: Vulnerability exists in specific workflows within the IPS Manager; all deployments using affected versions should be considered vulnerable.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of the IPS Manager leading to network-wide IPS bypass, lateral movement, data exfiltration, and persistent backdoor installation.

🟠

Likely Case

Attacker gains administrative control of IPS Manager, disables security policies, and uses the system as a foothold for further attacks.

🟢

If Mitigated

Attack is blocked at network perimeter or detected before code execution completes, limiting impact to failed exploitation attempts.

🌐 Internet-Facing: HIGH - Unauthenticated remote exploitation makes internet-facing instances immediate targets for automated attacks.
🏢 Internal Only: HIGH - Even internally accessible instances are vulnerable to internal attackers or compromised internal systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Insecure deserialization vulnerabilities are frequently weaponized quickly; unauthenticated nature makes this particularly dangerous.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Trellix advisory for specific patched version

Vendor Advisory: https://thrive.trellix.com/s/article/000013623

Restart Required: Yes

Instructions:

1. Review Trellix advisory 000013623. 2. Download and apply the latest IPS Manager patch from Trellix. 3. Restart the IPS Manager service. 4. Verify patch installation.

🔧 Temporary Workarounds

Network Isolation

all

Restrict network access to IPS Manager to only trusted administrative networks

Use firewall rules to limit access to specific source IPs/networks

Web Application Firewall

all

Deploy WAF with deserialization attack detection rules

🧯 If You Can't Patch

  • Immediately isolate the IPS Manager from internet and untrusted networks
  • Implement strict network segmentation and monitor all traffic to/from the IPS Manager

🔍 How to Verify

Check if Vulnerable:

Check IPS Manager version against affected versions listed in Trellix advisory 000013623

Check Version:

Check version through IPS Manager web interface or installation directory properties

Verify Fix Applied:

Verify installed version matches or exceeds patched version from advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual deserialization errors in application logs
  • Unexpected process creation from IPS Manager
  • Authentication bypass attempts

Network Indicators:

  • Unusual outbound connections from IPS Manager
  • Exploit kit traffic patterns to IPS Manager ports

SIEM Query:

source="IPS Manager" AND (event_type="deserialization" OR process_name="cmd.exe" OR process_name="powershell.exe")
