A format string vulnerability in Zyxel NAS326 firmware versions prior to V5.21(AAZF.12)C0 could allow an attacker to achieve unauthorized remote code execution via a crafted UDP packet.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
