Summary
WAGO: Unauthenticated Configuration Export in web-based management in multiple devices
Notes
Summary: A vulnerability in the web-based management (WBM) of WAGOs programmable logic controller (PLC) could allow an unauthenticated remote attacker to retrieve sensitive information.
Impact: 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.
Remediation: Install FW22 Patch 1
CVE-2022-3738

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.
