What to do
AI-suggested
To mitigate CVE-2024-45887, organizations should immediately restrict access to the DrayTek Vigor3900 management interface to trusted administrators only, ideally via isolated management VLANs or VPNs. Implement strong authentication controls, including multi-factor authentication, to reduce the risk of credential compromise. Monitor device logs for unusual activity related to the 'doOpenVPN' action or unexpected command execution attempts. Network segmentation should be enforced to limit the impact of a compromised device. Until an official patch is released, consider disabling the vulnerable web management interface if operationally feasible or restrict access to it via firewall rules. Regularly check for firmware updates from DrayTek and apply patches promptly once available. Conduct internal vulnerability assessments and penetration tests focusing on router management interfaces to identify similar weaknesses. Educate administrators about the risks of command injection and the importance of secure configuration management.
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 `doOpenVPN.`
