Summary
Several vulnerabilities have been identified in the web-based management of WAGO devices utilized in
Endress+Hauser IoT solutions. WAGO has provided fixes for these vulnerabilities, which have been
integrated into the solutions by Endress+Hauser. Additionally, a guideline on secure operation of these
solutions has been made available.
Details
Impact
With Cross-Site-Scripting it would be possible to attack a user's Web Browser, thereby potentially leaking
data, including personal and device data, to other 3rd parties. In case of leaked backup data, then credentials
used to authenticate with the remote services are also compromised.\
If the attacker has physical access to the component, then
* The devices connected to the components may no longer be available in Netilion.
* The data received by Netilion from the connected devices could be manipulated data.
* The components could be a vector in other cyber-attacks.
* Data from the components and connected devices could be leaked to 3rd parties.
Mitigation
If an immediate firmware update is not possible, the only way to prevent an attack is to prevent the access of
the Web Based Management tool from the internet. This can be achieved by using a network element, such
as a router, which hides and secures the components from the internet.
Remediation
Endress+Hauser provides updated firmware versions for the related components from WAGO which fixes the
vulnerability. Endress+Hauser strongly recommends customers to update to the new fixed version. For
support, please contact your local service center.

Critical 9.8
WAGO: Missing Authentication for Critical Function
The configuration backend allows an unauthenticated user to write arbitrary data with root privileges to the storage, which could lead to unauthenticated remote code execution and full system compromise.

Critical 9.8
WAGO: WBM Command Injection in multiple products
In multiple products of WAGO a vulnerability allows an unauthenticated, remote attacker to create new users and change the device configuration which can result in unintended behaviour, Denial of Service and full system compromise.

Medium 6.1
WAGO: Reflective Cross-Site Scripting
The configuration backend of the web-based management is vulnerable to reflected XSS (Cross-Site Scripting) attacks that targets the users browser. This leads to a limited impact of confidentiality and integrity but no impact of availability.

Medium 5.3
WAGO: Origin validation error through CORS misconfiguration
A CORS Misconfiguration in the web-based management allows a malicious third party webserver to misuse all basic information pages on the webserver. In combination with CVE-2022-45138 this could lead to disclosure of device information like CPU diagnostics. A…
