CVE-2024-41689
📋 TL;DR
This vulnerability allows attackers with physical access to extract WPA/WPS credentials stored in plaintext within the SyroTech SY-GPON-1110-WDONT router firmware. By reverse engineering the firmware, attackers can bypass Wi-Fi authentication and gain network access. Only users of this specific router model are affected.
💻 Affected Systems
- SyroTech SY-GPON-1110-WDONT Router
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker gains full access to Wi-Fi network, enabling man-in-the-middle attacks, data interception, and lateral movement to connected devices.
Likely Case
Local attacker with physical access extracts credentials and joins the Wi-Fi network for unauthorized access.
If Mitigated
With proper physical security, risk is minimal as exploitation requires direct physical access to the router.
🎯 Exploit Status
Exploitation requires physical access, firmware extraction tools, and reverse engineering skills. No authentication is needed once physical access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor for latest firmware update
Vendor Advisory: https://www.cert-in.org.in/s2cMainServlet?pageid=PUBVLNOTES01&VLCODE=CIVN-2024-0225
Restart Required: Yes
Instructions:
1. Check SyroTech website for firmware updates. 2. Download latest firmware. 3. Access router admin interface. 4. Upload and apply firmware update. 5. Reboot router.
🔧 Temporary Workarounds
Physical Security Enhancement
allSecure router in locked cabinet or restricted area to prevent physical access.
Wi-Fi Credential Rotation
allRegularly change WPA/WPS passwords to limit exposure if credentials are extracted.
🧯 If You Can't Patch
- Implement strict physical access controls to prevent unauthorized handling of router
- Disable WPS feature if not needed and use strong WPA2/WPA3 passwords only
🔍 How to Verify
Check if Vulnerable:
Check router model and firmware version against vendor advisory. If using SyroTech SY-GPON-1110-WDONT with unpatched firmware, assume vulnerable.Check Version:
Login to router admin interface and check firmware version in system status pageVerify Fix Applied:
After firmware update, verify new firmware version is installed and check vendor confirmation that patch encrypts stored credentials.📡 Detection & Monitoring
