Technical details

The vulnerability is an OS command injection flaw (CWE-78) in the dray_apm component of DrayTek VigorAP access points. The vulnerable code fails to properly validate UDP message content following a START_SPEED_TEST message, allowing special command characters to pass through unfiltered before execution. An unauthenticated remote attacker can send a crafted UDP packet to trigger the injection, resulting in arbitrary command execution with root privileges on the device. No authentication or user interaction is required. Firmware updates are available for all affected models.
