CVE-2025-15428
📋 TL;DR
This CVE describes a remote buffer overflow vulnerability in UTT 进取 512W router firmware version 1.7.7-171114. Attackers can exploit the strcpy function in the /goform/formRemoteControl endpoint to execute arbitrary code or crash the device. Organizations using this specific router model and firmware version are affected.
💻 Affected Systems
- UTT 进取 512W router
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network infiltration, and persistent backdoor installation.
Likely Case
Device crash causing denial of service, or limited code execution depending on exploit sophistication.
If Mitigated
Denial of service only if exploit attempts are blocked by network controls.
🎯 Exploit Status
Public proof-of-concept exploit is available on GitHub. The vendor has not responded to disclosure attempts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch exists. Consider replacing affected devices with supported alternatives.
🔧 Temporary Workarounds
Block Remote Access
linuxDisable remote administration and block access to the vulnerable endpoint via firewall rules.
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
Network Segmentation
allIsolate affected routers in separate VLANs with strict access controls.
🧯 If You Can't Patch
- Replace affected routers with supported models from vendors that provide security updates.
- Implement strict network monitoring and intrusion detection for exploit attempts.
🔍 How to Verify
Check if Vulnerable:
Check router web interface or CLI for firmware version 1.7.7-171114.Check Version:
Check router admin interface at http://[router-ip]/ or use telnet/ssh if enabled.Verify Fix Applied:
Verify firmware version has changed from 1.7.7-171114 (no official fix exists).📡 Detection & Monitoring
Log Indicators:
- HTTP POST requests to /goform/formRemoteControl with long Profile parameters
- Router crash/reboot logs
Network Indicators:
- Unusual HTTP traffic to router management interface
- Exploit pattern matching in network traffic
SIEM Query:
source="router_logs" AND uri="/goform/formRemoteControl" AND (param_length>100 OR contains(param,"Profile"))
