AI-suggested

To mitigate CVE-2024-45885, organizations should immediately restrict access to the management interface of DrayTek Vigor3900 devices, limiting it to trusted administrative networks and using VPNs or secure jump hosts where possible. Enforce strong, unique authentication credentials and consider multi-factor authentication if supported. Monitor router logs and network traffic for unusual command execution patterns or unauthorized access attempts. Disable or restrict the use of the 'autodiscovery_clear' function if configurable. Network segmentation should be employed to isolate management interfaces from general user networks. Regularly check for firmware updates from DrayTek and apply patches promptly once available. Additionally, conduct vulnerability scans and penetration tests focused on router management interfaces to detect potential exploitation attempts. Implement strict change management and incident response plans to quickly address any signs of compromise.

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 `autodiscovery_clear.`
