User InteractionNone needed
Summary

Unauthenticated attackers can change the password of any user in Industrial Edge Management, allowing them to impersonate valid users and gain full system access. This affects all versions prior to 1.3. The vulnerability enables attackers to take over administrative accounts without requiring any valid credentials.

What this means
What could happen
An unauthenticated attacker on the network could change any user's password, gaining full access to Industrial Edge Management and potentially controlling connected engineering and manufacturing systems.
Who's at risk
Manufacturing facilities using Siemens Industrial Edge Management for automation and process control. This includes any organization relying on Industrial Edge for edge computing, device management, or manufacturing control system orchestration.
How it could be exploited
An attacker with network access to the Industrial Edge Management interface could send a specially crafted request to reset any user password without authentication. Once a password is changed, the attacker can log in as that user and perform any administrative actions the account allows.
