OS command execution via AP management injection
Published Jul 17, 2023 · Updated Oct 29, 2024
Command injection in Zyxel firewall and WLAN controller AP management allows remote attackers on the LAN to execute OS commands. Zyxel has not published the affected request field, processing routine, or operation that passes attacker-controlled data to a command interpreter. Exploitation requires an authorized administrator to add the attacker's IP address to the managed AP list beforehand, after which command execution can compromise the appliance.
