CVE-2024-3080
📋 TL;DR
CVE-2024-3080 is an authentication bypass vulnerability affecting certain ASUS router models that allows unauthenticated remote attackers to gain administrative access to the device. This affects users of vulnerable ASUS router models with default or custom configurations exposed to network access. The vulnerability stems from improper authentication implementation (CWE-287).
💻 Affected Systems
- ASUS router models (specific models not detailed in provided references)
⚠️ Manual Verification Required

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of router with administrative access, enabling attackers to reconfigure network settings, intercept traffic, deploy malware to connected devices, or use the router as a pivot point for further attacks.
Likely Case
Unauthenticated attackers gaining administrative access to exposed routers, potentially changing DNS settings, capturing credentials, or disabling security features.
If Mitigated
Limited impact if routers are behind firewalls, have restricted WAN access, or are on isolated networks with proper segmentation.
🎯 Exploit Status
Authentication bypass vulnerabilities typically have low exploitation complexity once the method is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Specific patched firmware versions should be obtained from ASUS
Vendor Advisory: https://www.asus.com/support/
Restart Required: Yes
Instructions:
1. Check ASUS support site for your router model. 2. Download latest firmware. 3. Log into router admin interface. 4. Navigate to firmware update section. 5. Upload and apply new firmware. 6. Reboot router.
🔧 Temporary Workarounds
Disable WAN Administration
allPrevents remote access to router administration interface from internet
Network Segmentation
allPlace routers in isolated network segments with strict firewall rules
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure to router administration interface
- Monitor router logs for unauthorized access attempts and configuration changes
🔍 How to Verify
Check if Vulnerable:
Check router firmware version against ASUS security advisories; attempt authentication bypass if authorized testingCheck Version:
Log into router web interface and check firmware version in administration sectionVerify Fix Applied:
Verify firmware version matches patched version from ASUS; test authentication functionality📡 Detection & Monitoring
Log Indicators:
- Unauthenticated access to admin pages
- Failed login attempts followed by successful access
- Configuration changes from unexpected IP addresses
Network Indicators:
- Unexpected traffic to router administration ports (typically 80, 443, 8080)
- Traffic patterns suggesting router compromise
