Default Administrator Password Change Not Enforced in Axxon One Web Client

publishedCWE-1393

Use of Default Password (CWE-1393) in the web client in AxxonSoft Axxon One before 3.0.0 on Windows and Linux allows a remote unauthenticated attacker to log in as the built-in administrator with the default credentials on a newly installed system, because the web client did not enforce the mandatory change of the default password on first login.
