39th percentile - higher than 39% of all known CVEs

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.

Risk Assessment

An attacker can cause device crash or gain ability to execute arbitrary code, potentially leading to integrity and availability breaches of network services.

Recommendation

Install the latest firmware patches and restrict management interface access, and implement device integrity monitoring.
