✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor was contacted but did not respond. Consider workarounds or replacement.
🔧 Temporary Workarounds
Disable Web Management Interface
allDisable the vulnerable web interface to prevent exploitation
Router-specific commands vary; check device documentation for disabling web interface
Restrict Network Access
linuxBlock external access to router management interface
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Segment affected routers in isolated network zones
- Implement strict firewall rules to block all external access to management interfaces
🔍 How to Verify
Check if Vulnerable:
Test if /reqproc/proc_post endpoint responds to manipulated goformId parameter requestsCheck Version:
Check router web interface or use telnet/ssh to query firmware versionVerify Fix Applied:
Verify web interface is disabled or inaccessible from untrusted networks📡 Detection & Monitoring
Log Indicators:
- Unusual requests to /reqproc/proc_post with manipulated parameters
- Multiple failed authentication attempts followed by information disclosure requests
Network Indicators:
- External IP addresses accessing router management ports
- Unusual traffic patterns to /reqproc/proc_post endpoint
SIEM Query:
source_ip=external AND dest_port IN (80,443) AND uri_path="/reqproc/proc_post" AND query_string CONTAINS "goformId"
