CVE-2024-25568
📋 TL;DR
This CVE describes an OS command injection vulnerability in specific ELECOM wireless LAN routers that allows an unauthenticated attacker on the same network to execute arbitrary operating system commands by sending a specially crafted request. Affected users include anyone using WRC-X3200GST3-B v1.25 and earlier, WRC-G01-W v1.24 and earlier, or WMC-X1800GST-B v1.41 and earlier routers.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the router allowing attacker to install persistent backdoors, intercept all network traffic, pivot to other devices on the network, or brick the device.
Likely Case
Attacker gains full control of the router to monitor network traffic, modify DNS settings, or use the router as a foothold for further attacks on the internal network.
If Mitigated
Limited impact if network segmentation isolates the router management interface and proper access controls are implemented.
🎯 Exploit Status
Unauthenticated exploitation from the local network makes this particularly dangerous. No authentication required to trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: WRC-X3200GST3-B v1.26, WRC-G01-W v1.25, WMC-X1800GST-B v1.42
Vendor Advisory: https://www.elecom.co.jp/news/security/20240326-01/
Restart Required: Yes
Instructions:
1. Log into router web interface. 2. Navigate to firmware update section. 3. Download latest firmware from ELECOM website. 4. Upload and apply firmware update. 5. Reboot router after update completes.
🔧 Temporary Workarounds
Network Segmentation
allIsolate router management interface to dedicated VLAN or restrict access to trusted management hosts only.
Access Control Lists
allImplement firewall rules to restrict access to router management interface from unauthorized hosts.
🧯 If You Can't Patch
- Replace affected routers with non-vulnerable models immediately.
- Isolate affected routers in a dedicated network segment with strict firewall rules preventing lateral movement.
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface or SSH if enabled. Compare against affected versions listed in CVE.Check Version:
Check via router web interface under System Information or Settings > Firmware Update sections.Verify Fix Applied:
Verify firmware version has been updated to patched versions: WRC-X3200GST3-B v1.26+, WRC-G01-W v1.25+, WMC-X1800GST-B v1.42+.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests to router management interface
- Multiple failed authentication attempts followed by successful command execution
- Unexpected system processes or services running
Network Indicators:
- Unusual outbound connections from router to external IPs
- DNS queries to suspicious domains from router
- Unexpected network traffic patterns from router
SIEM Query:
