AI-suggested
Organizations should immediately restrict administrative access to DrayTek Vigor3900 routers to trusted personnel and secure management interfaces using strong authentication methods such as multi-factor authentication. Network segmentation should be enforced to limit access to router management interfaces from untrusted networks. Monitoring and logging of administrative activities should be enhanced to detect suspicious command execution attempts. Until official patches are released by DrayTek, consider deploying compensating controls such as disabling unnecessary services or interfaces that could be leveraged for exploitation. Regularly check for firmware updates from DrayTek and apply them promptly once available. Conduct internal audits to ensure no unauthorized accounts or weak credentials exist on these devices. Additionally, implement network intrusion detection systems (NIDS) tuned to detect anomalous command injection patterns or unusual traffic flows associated with compromised routers. Finally, educate administrators about the risks of credential compromise and enforce strict password policies.
Description
DrayTek Vigor3900 v1.5.1.6 was discovered to contain an authenticated command injection vulnerability via the name parameter in the run_command function.
