CVE-2026-121022
Default Administrator Password Change Not Enforced in Axxon One Web Client
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.
Fixes and workarounds
Fix
Upgrade Axxon One to version 3.0.0 or later, where the web client requires the default password to be changed on first login.
Source: CNA: AxxonSoftWorkaround
On earlier versions, change the default administrator password in the desktop client immediately after installation, before the web server is reachable from the network.
