What to do
AI-suggested
1. Monitor DrayTek official channels for firmware updates addressing CVE-2024-51257 and apply patches immediately upon release. 2. Until patches are available, restrict network access to the router's management interface (mainfunction.cgi) by implementing strict firewall rules, allowing only trusted IP addresses. 3. Disable remote management features if not required, especially web-based interfaces accessible from untrusted networks. 4. Employ network segmentation to isolate critical infrastructure and limit lateral movement in case of compromise. 5. Regularly audit router configurations and logs for suspicious activity indicative of exploitation attempts. 6. Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection patterns targeting DrayTek devices. 7. Educate network administrators on the risks and signs of exploitation to enable rapid response.
Description
DrayTek Vigor3900 1.5.1.3 allows attackers to inject malicious commands into mainfunction.cgi and execute arbitrary commands by calling the doCertificate function.
