CasaOS is an open-source Personal Cloud system. Due to a lack of IP address verification an unauthenticated attackers can execute arbitrary commands as root on CasaOS instances. The problem was addressed by improving the detection of client IP addresses in 391dd7f. This patch is part of CasaOS 0.4.4. Users should upgrade to CasaOS 0.4.4. If they can’t, they should temporarily restrict access to CasaOS to untrusted users, for instance by not exposing it publicly.
