Title
DrayTek VigorAP Multiple Models Buffer Overflow via setLan
Summary
Multiple DrayTek VigorAP models contain a buffer overflow vulnerability in the setLan function. The vulnerability is caused by missing length checks during memory copy operations involving the lanVlanId0, lanIp, and lanNetmask fields. A remote attacker can trigger this vulnerability via crafted input, causing a denial of service or potentially executing arbitrary commands. Exploitation requires valid administrative credentials for the device's web management interface.
