Executive Summary

This is an OS command injection vulnerability in multiple DrayTek VigorAP models. It exists in the setcamset function due to insufficient filtering of the selectSlaves field. A remote attacker with valid administrative credentials for the web management interface can exploit this to execute arbitrary commands with root privileges.

Detection Guidance

To detect this vulnerability, check if any of the affected DrayTek VigorAP models (918R, 960C, 1060C, 906, 912C, 903) are present on your network. Inspect the web management interface for the setcamset function and test if the selectSlaves field allows command injection by attempting to inject simple commands like 'id' or 'whoami'.

Impact Analysis

An attacker could gain full control of the affected device, allowing them to manipulate network traffic, install malware, or use the device as a pivot point for further attacks within the network. This could lead to data breaches or unauthorized access to sensitive information.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements under GDPR or HIPAA. Organizations using affected devices may face legal penalties, fines, or reputational damage due to non-compliance with data protection regulations.

Mitigation Strategies

Immediately update the firmware of all affected DrayTek VigorAP devices to the latest version provided by DrayTek. Restrict access to the web management interface by limiting administrative access to trusted IP addresses only. Monitor network traffic for suspicious activity related to command execution attempts.
