CVE-2025-10171
📋 TL;DR
A buffer overflow vulnerability in UTT 1250GW devices allows remote attackers to execute arbitrary code or cause denial of service. This affects all versions up to 3.2.2-200710. Remote exploitation is possible without authentication.
💻 Affected Systems
- UTT 1250GW
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network infiltration, and persistent backdoor installation.
Likely Case
Remote code execution allowing attackers to gain control of the device, modify configurations, and pivot to internal networks.
If Mitigated
Denial of service if exploit fails or is blocked, potentially disrupting network connectivity.
🎯 Exploit Status
Public exploit code is available on GitHub. Remote exploitation requires no authentication. The vulnerability is in formConfigApConfTemp endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available - vendor did not respond to disclosure
Restart Required: Yes
Instructions:
No official patch available. Consider upgrading to any firmware version beyond 3.2.2-200710 if available, or replace with alternative hardware.
🔧 Temporary Workarounds
Network Segmentation
allIsolate UTT 1250GW devices from internet and restrict access to management interface
Access Control Lists
allImplement firewall rules to block external access to port 80/443 on affected devices
🧯 If You Can't Patch
- Immediately disconnect vulnerable devices from internet-facing networks
- Implement strict network segmentation and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface at http://device-ip/ or via SSH using version commandCheck Version:
Check web interface or use vendor-specific CLI commands for version informationVerify Fix Applied:
Verify firmware version is above 3.2.2-200710. No official fix exists, so verification requires vendor confirmation.📡 Detection & Monitoring
