Wago web-based management of multiple products has a vulnerability which allows an local authenticated attacker to change the passwords of other non-admin users and thus to escalate non-root privileges.
On affected Wago products an remote attacker with administrative privileges can access files to which he has already access to through an undocumented local file inclusion. This access is logged in a different log file than expected.
The vulnerability allows a remote unauthenticated attacker to download a backup file, if one exists. That backup file might contain sensitive information like credentials and cryptographic material. A valid user has to create a backup after the last reboot for this attack to be successfull.
