More than 100,000 Zyxel firewalls, VPN gateways, and access point controllers contain a hardcoded admin-level backdoor account that can grant attackers root access to devices via either the SSH interface or the web administration panel.
Installing patches removes the backdoor account, which, according to Eye Control researchers, uses the "Zyfwp" username and the "PrOw!aN fXp" password.
"The plaintext password was visible in one of the binaries on the system," the Dutch researchers said in a report published before the Christmas 2020 holiday.
