What to do
AI-suggested
1. Immediately restrict administrative access to the DrayTek Vigor3900 management interface to trusted IP addresses and networks only, preferably via VPN or secure management channels. 2. Enforce strong, unique passwords and disable default credentials to reduce the risk of unauthorized authentication. 3. Monitor router logs and network traffic for unusual commands or activity related to the 'cgi-bin/mainfunction.cgi' endpoint, especially requests containing the 'setSWMGroup' action parameter. 4. Disable or limit CGI interface access if not required for operational purposes. 5. Apply firmware updates or patches from DrayTek as soon as they become available to address this vulnerability. 6. Consider network segmentation to isolate critical router management interfaces from general user networks. 7. Conduct regular security audits and penetration testing to detect potential exploitation attempts. 8. Implement multi-factor authentication for router management access if supported.
Description
DrayTek Vigor3900 1.5.1.3 contains a post-authentication command injection vulnerability. This vulnerability occurs when the `action` parameter in `cgi-bin/mainfunction.cgi` is set to `setSWMGroup.`
