CVE-2025-15429
📋 TL;DR
A remote buffer overflow vulnerability in UTT 进取 512W firmware version 1.7.7-171114 allows attackers to execute arbitrary code or cause denial of service by exploiting the strcpy function in the /goform/formConfigCliForEngineerOnly endpoint. This affects users of this specific router model with the vulnerable firmware. The vulnerability is remotely exploitable without authentication.
💻 Affected Systems
- UTT 进取 512W router
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network infiltration, data theft, and persistent backdoor installation.
Likely Case
Remote denial of service causing router crashes and network disruption, potentially leading to remote code execution.
If Mitigated
Limited impact if device is behind strict network segmentation with no external access.
🎯 Exploit Status
Public proof-of-concept exploit exists on GitHub. The vulnerability requires no authentication and has simple exploitation vectors.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider replacing device or implementing workarounds.
🔧 Temporary Workarounds
Block vulnerable endpoint
linuxUse firewall rules to block access to the /goform/formConfigCliForEngineerOnly endpoint
iptables -A INPUT -p tcp --dport 80 -m string --string "/goform/formConfigCliForEngineerOnly" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string "/goform/formConfigCliForEngineerOnly" --algo bm -j DROP
Disable web management interface
allTurn off the web management interface if not required
Check router admin interface for web management toggle
🧯 If You Can't Patch
- Isolate the router in a separate VLAN with strict network segmentation
- Implement strict firewall rules to limit access to router management interfaces
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface at http://[router-ip]/status.asp or via SSH if enabled. Look for version 1.7.7-171114.Check Version:
curl -s http://[router-ip]/status.asp | grep -i versionVerify Fix Applied:
No official fix available to verify. Verify workarounds by testing if /goform/formConfigCliForEngineerOnly endpoint is inaccessible.📡 Detection & Monitoring
Log Indicators:
- Multiple requests to /goform/formConfigCliForEngineerOnly with long parameters
- Router crash/restart logs
- Unusual outbound connections from router
Network Indicators:
- HTTP POST requests to /goform/formConfigCliForEngineerOnly with unusually long addCommand parameter
- Sudden router unresponsiveness followed by abnormal traffic patterns
SIEM Query:
