Technical details

The vulnerability is a classic buffer overflow (CWE-120) in the setLan function caused by missing length validation during memory copy operations on the lanVlanId0, lanIp, and lanNetmask fields. The flaw can be triggered remotely via crafted HTTP requests to the device's web management interface, but requires valid administrative credentials for authentication. Successful exploitation could result in denial of service or remote code execution with device privileges. Firmware patches are available for all affected models: VigorAP 918R (1.4.11+), 960C (1.4.12+), 1060C (1.4.12+), 906 (1.4.13+), 912C (1.4.15+), and 903 (1.4.22+).
