CVE-2020-11966Network attack vector

Unauthenticated root password change via reset_password

Published Apr 21, 2020 · Updated Aug 4, 2024

Password reset in the IQrouter web panel 3.3.1 and earlier allows remote attackers to set an arbitrary root password during initial setup. The Lua reset_password function accepts a remotely supplied replacement for the root credential through the web panel without a prior login. Reachability is limited to an unconfigured device; Evenroute states that forced initial configuration requires a secure password and disputes the issue's validity.
