CVE-2026-2980
📋 TL;DR
A buffer overflow vulnerability in the UTT HiPER 810G router's administrative interface allows remote attackers to execute arbitrary code by manipulating password parameters. This affects all versions up to 1.7.7-1711. Attackers can exploit this without authentication to potentially take full control of affected devices.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, credential theft, network pivoting, and persistent backdoor installation.
Likely Case
Device takeover enabling traffic interception, network disruption, and credential harvesting from connected systems.
If Mitigated
Limited impact if devices are behind firewalls with restricted administrative access, though exploitation remains possible.
🎯 Exploit Status
Proof-of-concept exploit code is publicly available on GitHub, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch is available. Check vendor website for firmware updates beyond version 1.7.7-1711.
🔧 Temporary Workarounds
Disable Administrative Web Interface
allDisable the vulnerable web interface to prevent remote exploitation
Access router CLI via SSH/Telnet and disable web admin interface (specific commands vary by firmware)
Restrict Administrative Access
allLimit administrative interface access to specific trusted IP addresses only
Configure firewall rules to restrict access to port 80/443 to trusted management IPs
🧯 If You Can't Patch
- Isolate affected routers in separate VLANs with strict firewall rules
- Implement network segmentation to limit lateral movement if device is compromised
🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface at http://[router-ip]/ or via CLI command 'show version'Check Version:
ssh admin@[router-ip] 'show version' or check web interface System Status pageVerify Fix Applied:
Verify firmware version is above 1.7.7-1711 if vendor releases patch📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/setSysAdm with long password parameters
