CVE-2025-15462
📋 TL;DR
A buffer overflow vulnerability in the UTT 进取 520W router firmware allows remote attackers to execute arbitrary code by exploiting the strcpy function in the ConfigAdvideo component. This affects version 1.7.7-180627 of the router firmware. Attackers can exploit this without authentication to potentially take full control of affected devices.
💻 Affected Systems
- UTT 进取 520W router
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, data theft, network infiltration, and use as a botnet node.
Likely Case
Remote code execution allowing attackers to modify router settings, intercept traffic, or launch attacks on internal networks.
If Mitigated
Limited impact if devices are behind firewalls with strict inbound filtering and network segmentation.
🎯 Exploit Status
Proof-of-concept exploit code is publicly available, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch available. Vendor did not respond to disclosure. Consider replacing affected devices with supported alternatives.
🔧 Temporary Workarounds
Network Segmentation
allIsolate affected routers in separate network segments to limit potential damage.
Access Control Lists
allImplement strict firewall rules to limit access to router management interfaces.
🧯 If You Can't Patch
- Replace affected routers with supported devices from vendors that provide security updates
- Implement network monitoring and intrusion detection specifically for router compromise indicators
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via web interface or SSH. If version is 1.7.7-180627, device is vulnerable.
Check Version:
Check via router web interface at System Status or via SSH with 'show version' command
Verify Fix Applied:
No fix available to verify. Consider device replacement as primary remediation.
