Search an embedded database of 40+ known router vulnerabilities by brand, model, or CVE ID. Each entry includes a CVSS severity score, affected firmware versions, and recommended remediation steps. Use this to check whether your router model has documented security issues.
| CVE ID | Brand | Model(s) | CVSS | Severity | Description | Fix |
|---|
CVE (Common Vulnerabilities and Exposures) is a standardized system for identifying and cataloging security vulnerabilities. Each CVE entry has a unique ID (like CVE-2024-3080), a description, and a severity score. For router owners, checking CVEs for your specific model helps you understand whether your device has known security flaws that attackers could exploit.
Routers are high-value targets because they sit at the boundary of your network. A compromised router can intercept all your traffic, redirect DNS queries to malicious servers, and serve as a launching point for attacks on your other devices. Regularly checking for vulnerabilities and updating your firmware is critical.
The Common Vulnerability Scoring System (CVSS) rates vulnerabilities on a scale of 0 to 10. Higher scores indicate more severe vulnerabilities that should be patched immediately:
| CVSS Score | Rating | Action Required |
|---|---|---|
| 9.0 - 10.0 | Critical | Patch immediately or take device offline |
| 7.0 - 8.9 | High | Patch within 24-48 hours |
| 4.0 - 6.9 | Medium | Patch within your normal update cycle |
| 0.1 - 3.9 | Low | Patch when convenient |
Pro Tip: Do not rely solely on CVSS scores to prioritize patching. A medium-severity vulnerability that is being actively exploited in the wild is more urgent than a critical vulnerability with no known exploit. Check vendor advisories and threat intelligence feeds for exploitation status. Always change your admin password after applying security patches.
Certain vulnerability classes appear repeatedly across router brands. Understanding these patterns helps you assess your risk even if your exact model is not listed above:
| Vulnerability Type | Frequency | Typical Impact | Prevention |
|---|---|---|---|
| Command Injection | Very Common | Full device compromise (RCE) | Update firmware, disable remote management |
| Authentication Bypass | Common | Unauthorized admin access | Strong password, restrict admin to LAN |
| Buffer Overflow | Common | Remote code execution | Firmware updates, disable unused services |
| Default Credentials | Very Common | Full device access | Change passwords on first login |
| Path Traversal | Common | Config/credential disclosure | Update firmware, restrict web access |
If you find your router model in the database above, take these steps in order of priority:
Many of the CVEs in our database affect routers that have reached end of life (EOL) — meaning the manufacturer no longer provides security updates. Running an EOL router is one of the biggest security risks for a home network, yet millions of devices remain in use worldwide.
If your router has not received a firmware update in over two years, it is likely EOL. Upgrade to a supported model that receives regular security patches. Modern routers with WPA3 support and active firmware development provide significantly better security. Consider models that support WPA3 encryption and built-in VPN capabilities.
Beyond patching specific CVEs, these proactive measures protect against both known and unknown vulnerabilities:
Log in to your router admin panel (usually at 192.168.1.1) and look for a section labeled "Firmware Version," "System Information," or "Status." The version number is typically shown on the main dashboard. See our router login guide if you need help accessing the admin panel.
This database covers notable vulnerabilities but is not exhaustive. Search your router model on the National Vulnerability Database (NVD) or check your manufacturer's security advisories page. The absence of a CVE does not mean your router is secure — it may have undisclosed vulnerabilities.
Yes. Router vulnerabilities are actively exploited by botnets, state-sponsored actors, and cybercriminals. Critical vulnerabilities like authentication bypass and RCE can give attackers full control of your router and access to all network traffic. This is why firmware updates are essential.
Check at least quarterly, or whenever a major vulnerability makes the news. Subscribe to your router manufacturer's security mailing list for automatic notifications. Also check after any unusual network behavior like unexpected DNS changes or slow performance.
End of life means the manufacturer no longer provides firmware updates, security patches, or technical support. Any new vulnerabilities discovered will never be fixed. If your router is EOL, replace it with a currently supported model to maintain security.
Yes. Remote management (accessing the router admin panel from the WAN/internet side) is the most common attack vector for router CVEs. Unless you specifically need it, disable remote management and only access the admin panel from your local network.
ISP-provided gateways can be vulnerable. ISPs are responsible for pushing firmware updates, but they are often slow to patch. Check our database for your ISP gateway model. If vulnerabilities are found and no update is available, consider using your ISP gateway in bridge mode with your own router for better security.
