CVE-2024-12011

7.6 HIGH

📋 TL;DR

CVE-2024-12011 is a buffer over-read vulnerability in the 130.8005 TCP/IP Gateway firmware that allows unauthenticated attackers to leak authentication tokens from memory. This enables authentication bypass and potential unauthorized access to affected systems. Organizations using this specific gateway firmware version are at risk.

💻 Affected Systems

Products:
  • 130.8005 TCP/IP Gateway
Versions: Firmware version 12h
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects the specific firmware version mentioned; other versions may be unaffected.

⚠️ 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).

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 system compromise via stolen admin credentials leading to industrial control system manipulation, data theft, or operational disruption.

🟠

Likely Case

Unauthorized access to the gateway's web interface, configuration changes, and potential lateral movement within the network.

🟢

If Mitigated

Limited impact if network segmentation prevents access to vulnerable systems and monitoring detects anomalous authentication attempts.

🌐 Internet-Facing: HIGH - Remote unauthenticated exploitation makes internet-facing systems immediate targets.
🏢 Internal Only: MEDIUM - Internal attackers or malware could exploit this to move laterally within the network.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires understanding of the memory leak to extract valid tokens, but no authentication is needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor for updated firmware version

Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2024-12011

Restart Required: Yes

Instructions:

1. Contact the vendor for patched firmware. 2. Backup current configuration. 3. Apply firmware update following vendor procedures. 4. Verify functionality post-update.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate vulnerable gateways from untrusted networks and restrict access to authorized IPs only.

Configure firewall rules to block external access to TCP ports used by the gateway

Access Control Lists

all

Implement strict network ACLs to limit which systems can communicate with the vulnerable gateway.

Add ACL rules on network devices to permit only necessary traffic

🧯 If You Can't Patch

  • Implement network segmentation to isolate vulnerable systems
  • Deploy intrusion detection systems to monitor for exploitation attempts
  • Enforce strict authentication policies and monitor for unusual login patterns

🔍 How to Verify

Check if Vulnerable:

Check firmware version via web interface or CLI: version should show '12h' if vulnerable.

Check Version:

Check device web interface or use vendor-specific CLI command for version information

Verify Fix Applied:

Verify firmware version has been updated to a version newer than 12h and test authentication bypass attempts fail.

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed authentication attempts followed by successful login from new IP
  • Unusual memory usage patterns in system logs
  • Authentication token reuse from different source IPs

Network Indicators:

  • Unusual HTTP requests to web server endpoints
  • Traffic patterns suggesting memory probing
  • Authentication requests with stolen tokens

SIEM Query:

source="gateway_logs" AND (event_type="auth_failure" OR event_type="auth_success") | stats count by src_ip, user | where count > threshold
