CVE-2025-65008
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary system commands on affected WODESYS routers via the langGet parameter in the adm.cgi endpoint. Attackers can gain full control of the router without authentication. All users of vulnerable WODESYS router models are affected.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of router allowing attackers to intercept all network traffic, pivot to internal networks, install persistent backdoors, or brick the device.
Likely Case
Attackers gain router administrative access to monitor traffic, change DNS settings, or use the router as a foothold for further attacks.
If Mitigated
Limited impact if routers are behind firewalls with strict inbound filtering and network segmentation.
🎯 Exploit Status
Exploitation requires simple HTTP requests to the vulnerable endpoint with crafted parameters. Public references suggest exploit details are available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch available. Monitor vendor website for firmware updates and apply immediately when released.
🔧 Temporary Workarounds
Block adm.cgi endpoint
linuxUse firewall rules to block access to the vulnerable adm.cgi endpoint
iptables -A INPUT -p tcp --dport 80 -m string --string "adm.cgi" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string "adm.cgi" --algo bm -j DROP
Disable web administration interface
allDisable remote web administration if not required
Check router settings for 'Remote Management' or 'Web Administration' and disable
🧯 If You Can't Patch
- Replace affected routers with different models from vendors with better security response
- Place routers behind dedicated firewalls with strict inbound filtering and IDS/IPS rules
🔍 How to Verify
Check if Vulnerable:
Test by sending HTTP request to router IP: http://[router-ip]/adm.cgi?langGet=;id (check for command output in response)Check Version:
Check router web interface or use nmap: nmap -sV -p 80,443 [router-ip]Verify Fix Applied:
Test same exploit attempt after applying mitigations - should no longer execute commands📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /adm.cgi with langGet parameter containing shell metacharacters
- Unusual command execution in router logs
- Multiple failed login attempts followed by successful access
Network Indicators:
- HTTP traffic to router admin interface containing shell commands in parameters
- Unusual outbound connections from router to external IPs
