Executive brief
DrayTek VigorAP access points are wireless network devices used to provide secure enterprise connectivity. A command injection vulnerability in the settings export function allows an authenticated administrator to execute arbitrary commands with root-level privileges. An attacker with valid admin credentials could use this to gain complete control of the access point and potentially compromise the entire network.
Technical details
This is an OS command injection vulnerability (CWE-78) in the ExportSettings function of multiple VigorAP models, caused by insufficient input filtering on the backupkey, backuptype, and realtime parameters before command execution. The attack requires valid administrative credentials to authenticate to the device's web management interface. A remote attacker can inject arbitrary shell commands through these fields to achieve command execution with root privileges. Patches are available in the form of firmware updates for each affected model (versions 1.4.11 to 1.4.22 depending on the model).
