Sources and claim methodology

Upstream source description

Multiple DrayTek VigorAP models contain a command injection vulnerability in the upload_settings.cgi interface. The vulnerability is caused by insufficient filtering before the restorekey field is concatenated into a shell command. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.
